Foreword:

Congratulations and thank you! You have just purchased the finest personal locator EPIRB

available on the market. Other brands merely attempt to meet the requirements established by

government regulatory agencies. ACR designed its Mini B300 to work in real life situations and

to save lives. It, therefore, exceeds many of the requirements established by authorities. By

purchasing this EPIRB you have distinguished yourself as one of the safest persons in boating.

To be a responsible EPIRB owner:

·Read this manual.

·Activate your EPIRB ONLY in an emergency.

·Mount your EPIRB in an easily accessible spot or store it in your ditch/emergency kit.

·Prepare an emergency evacuation plan and rehearse it.

·In a grave and imminent situation, where you have exhausted all other means of rescue,

activate your EPIRB and leave it “On”. Do not turn it Off and On in the misguided belief that

you are saving battery power.

·NEVER set off a false alarm.

Please call or write for answers to questions or for information on other safety products

manufactured by ACR Electronics, Inc.

SECTION 1 — INTRODUCTION

1.1 General

This manual provides installation, operation and maintenance instructions for the ACR/MINI

B300TM Emergency Position Indicating Radio Beacon (EPIRB), hereinafter referred to as the

Beacon. This section describes the characteristics and details of the Beacon (See Figure 1). A

Cognizant Authority Station License may be required to carry this unit. The Beacon comes with

a user replaceable 6 volt Lithium, Duracell DL223A, (or equivalent) battery. See installation

instructions page 5.

1.2 Purpose

The Beacon is an item of survival equipment and is designed to be carried on a person or

aboard vessels at sea and in port, so as to be readily available in any emergency. It may be used

on the deck of vessels, on survival craft, or may be attached to the latter with the provided

lanyard, as well as attached to survival suits, etc. When turned “ON”, it transmits tone

modulated signals (VHF) so that rescue aircraft or vessels equipped with suitable direction

finding receiving equipment can “home” to the transmitting unit.

1.3 Authorizations

The ACR/MINI B300TM Emergency Position Indicating Radio Beacon meets the requirements

of the FCC and the European Telecommunications Standards Institute, ETS 300 152, for

Marine use.

1.4 Characteristics

The ACR/MINI B300TM Beacon is an o-ring sealed battery operated unit. The Beacon case,

with its external antenna is waterproof. The semiconductor circuits are mounted within the case

assembly, which also contains the battery power supply. An “ON-OFF” switch is installed on

top of the Beacon, along with a light emitting diode (LED) operation indicator. The Beacon

may be carried on a person, stowed in any convenient place, mounted in a special bracket

aboard a vessel, or tied with its lanyard inside survival craft. The unit floats and is completely

waterproof.

SECTION 2 — INSTALLATION

2.1 General

The ACR/MINI B300TM Beacon has been designed for multi-purpose installation for survival

use, personnel, rafts, floats and survival craft. It should be carried with you or stowed where it

will be readily available in an emergency.

2.2 Battery Installation

1. Remove four (4) screws holding the top cap of the Beacon to the case. Use a no. 2 Phillips

screwdriver. Remove top cap and PC board from bottom case being careful not to disturb

any electronic components on the PC board.

2. Remove old battery and place new battery in battery clip with groove side of battery down

and flat side of battery up. Caution: Make sure flat side of battery is up. Otherwise, the

polarity of the battery would be reversed and damage to the battery will occur. The battery

also poses a possible fire, explosion, or burn hazard when placed in the battery clip upside

down. A semiconductor diode protects the electronics from damage due to battery reversal.

3. Put the battery expiration date on the flat side of the battery and on the EPIRB case with

ACR part no. A1-20-0857 or equivalent permanent shield label.

4. Grease the top cap o-ring with Dow Corning number 4 Silicone Grease, ACR Part no. A2-

09-0069.

5. Replace the four (4) screws holding the top cap to the bottom case of the Beacon. Make sure

screws are tight but do not use excessive torque, which could strip the threads in the top

cap.

2.3 Battery Date Code

A typical Duracell DL223A battery has a date code of 6J1313. The first alphanumeric character

of the code is always a number representing the last digit of the year of manufacture. The

second alphanumeric character of the code is always a letter, the position of which in the

alphabet represents the number of the month of manufacture. That is: A represents January, B

represents February, C represents March, etc.

Y1-03-0136 Rev. C6

The next two alphanumeric characters of the code represent the day of the month of

manufacture. Therefore, the date of manufacture for the date code 6J1313 is October 13, 1996.

2.4 Battery Expiry Date

The battery Expiry Date is obtained by adding the battery manufacturers rated replacement life

of 10 years to the date of manufacture. For example, a date code of 6J1313 would have a

Battery Expiry Date of October 13, 2006.

SECTION 3 — OPERATION

3.1 General

The EPIRB is designed to operate best when placed on a flat non-conductive surface or while

over water at sea. It should be operated in an area free of obstructions, which could absorb RF

energy and limit radiation patterns.

Position the antenna straight up (perpendicular to ground) and not pointing toward the receiving

station. Note that the radiation field null occurs directly off the end of the antenna.

Maintain a visual path where possible between the Beacon and the receiver, since beacons

characteristically transmit “line of sight”. The Beacon transmits on 121.5 MHz.

3.2 Manual Deployment

Remove the Beacon from its storage position and ensure that the antenna telescoping section is

fully extended and that the antenna is in an upright position. Break and remove the flip switch

seal. Flip the switch to the “ON” position. Red LED indicator will illuminate. The LED

indicator will remain on for 5 seconds indicating that the batteries are functional. After 5

seconds, the LED indicator will begin flashing, indicating that the transmitter is functioning

properly. If operated from the deck of the vessel, choose the most advantageous position free of

surrounding obstacles. If deployed in water, make sure that the antenna is positioned vertically

and the antenna itself is out of the water. It is preferable to hold the unit above the water, as

immersion reduces effectiveness.

SECTION 4 — MAINTENANCE

4.1 General

The Beacon has been designed for use with a minimum of maintenance required. A check list is

given in this section, and when accomplished periodically, should help to assure emergency

operation and extended life use.

Y1-03-0136 Rev. C7

4.2 Battery Check

1. The battery expiry date should always be placed on the battery and the outside of the

Beacon case. See 2.2 Battery Installation. Replace the battery immediately after extended

use or emergency and always on or before the battery expiry date. Use only a 6 volt Lithium

Duracell DL223A (or equivalent) battery.

2. Safety Precautions:

Warning: To avoid possible fire, explosion, leakage or burn hazard, do not open, recharge,

disassemble, heat above 71°C (160°F) or incinerate.

4.3 Inspection Check

The following checks should be made during the periodic servicing:

1. Check the antenna tip and telescoping sections for any signs of damage or corrosion.

2. Check the plastic covered portion of the antenna for any signs of chafing, wear, cracks, or

other damage, and signs of resultant corrosion beneath the covering.

3. Check the antenna socket at the cap surface for any sign of looseness or corrosion.

4. Check the Beacon housing for signs of damage or mishandling. Dents, or damage to the top

end could result in an operational malfunction during an emergency.

5. Check the lanyards for chafing, fraying or any damage. Check the lanyard anchor points for

chafing. Resecure the lanyards and check the knots for tightness.

6. Rinse the outside of the unit with fresh water frequently to remove any salt build-up on case

or exposed parts.
