Operation
Note: The test set must have a charged battery installed in order to operate.
See Changing the Battery or Cord Set in this manual.
TALK
Press once to go off-hook (connect). Press again or press MONITOR to go on-hook
(disconnect).
To conserve battery life, the test set will shut off 90 seconds after removal from the line.
MONITOR
Press once to monitor the line without disturbing data, signal, or voice communication.
Press repeatedly to alternate between Monitor mode and off.
To conserve battery life, the test set will shut off after 20 minutes of monitoring or
90 seconds after removal from the line.
MUTE
Press and release to stop transmitting over the line or to eliminate sidetones.
Press again to talk.

Dialing Features
PULSE
Pulse Dialing
With the test set connected to a communication line, press PULSE, then press TALK.
To mix pulse and tone dialing, select pulse as instructed above and dial the pulse digits. Then
press and dial the tone digits.
Notes:
• A called number with mixed digits will be stored in the Last Number Redial memory as
dialed.
• If the Last Number Redial function is used while in pulse mode, the number will be dialed
as a mix of pulse and tone digits. If used while in tone mode, all of the digits will be dialed
as tone digits.
The dialing mode automatically returns to tone-type dialing when the test set is removed from
the line or when the test set is switched off.
LNR/PAUSE
Last Number Redial / Pause
After going off-hook, press LNR/PAUSE (last number redial) to redial the last called number.
When programming, press LNR/PAUSE to insert a four-second pause in the dialing string.
STO
MEM
Store and Memory
The test set can store up to ten 24-digit telephone numbers, one under each of the
digits (0–9).
To store a telephone number:
1. While connected to a line and in the Talk mode, press STO.
2. Enter the telephone number.
3. Press MEM.
4. Press one of the digits (0–9).
In addition to digits, the memory will also store , , (flash) and (pause).
To recall a number, press MEM and then the storage location digit (0–9) while connected to a
line in the Talk mode.

Other Features
FLASH
Flash
Press FLASH to generate a timed line break.
SPKR
Speaker (45054 only)
The speaker allows One-Way Hands Free Operation (receive only).
• When in the Talk mode, press SPKR to use the speaker.
• When in the On-Hook mode, press SPKR to use the speaker. Press MONITOR to go on-
hook, or press TALK to go to the Talk mode.
VOL
Volume Control
To control the speaker volume, press VOL. The speaker is set to automatically start out at the
low setting. Press VOL to toggle between high and low volume.
Note: When using the high volume setting, the dial tone may fade. This does not indicate a
fault or a problem, and you may still dial out.
POL
Polarity
To determine the polarity, press POL. The LED will indicate polarity as follows:
• Red wire connected to ring (negative): Green LED
• Red wire connected to tip (positive): Red LED
Pressing POL while ringing will cause both LEDs to flash.
Use of the POL function will not disrupt data or speech.

Changing the Battery or Cord Set
Note: Replace the battery in less than one minute to retain the contents of the memory.
1. Disconnect the unit from the circuit.
2. Press MONITOR to go to On-Hook mode.
3. Remove the three screws and the cover.
4. Replace the battery or cord set, as shown. Observe polarity.
5. Replace the cover and screws.
Note: Skipping Steps 1 and 2 might cause the unit to malfunction. If the test set does not
restart after changing the battery, disconnect the battery for two minutes. Then proceed with
Step 4.

Using the Test Set for Troubleshooting Circuits
Some general troubleshooting procedures and tips are provided here. These procedures may
require other tools or equipment that are specific to the communications system installation
trade. For a complete selection of DSV (data-signal-voice) tools, please refer to a Greenlee
full-line catalog, a Greenlee DSV catalog, or visit our website at www.greenlee.textron.com.
RFI (radio
frequency
interference)
Split pair An unbalanced pair near a radio transmitter will
be prone to RFI. Adding radio filters can reduce
the interference on the line (the symptom), but
does not solve the imbalance (the problem). To
troubleshoot, break the circuit down into
sections and check each section for split pairs
or a resistive imbalance.
Improperly removed bridge taps may also
introduce RFI. Bridge taps, which were once used
for party-line service (multiple users sharing a
cable pair), were often disconnected but left in
place, with a stub section of cable still connected.
This stub section can act as an antenna and
induce radio signals into the circuit.
Ground fault Check for the presence of AC line voltage. If AC
line voltage is present, measure the level. If it is
typical line voltage, contact the local electric
utility.
A long run of telephone
cable near a power line Contact the local electric utility.
Power hum Cable imbalance Break the circuit down into sections and check
each section for an imbalance.
Momentary or impulse
noise This may be due to an unbalanced cable, nearby
power switch gear, or similar equipment.
Popping, crackling The customer has an older carbon transmitter
type of telephone.
Noise Hiss (white noise);
pulse dialing causes a
momentary change in
the sound of the noise
This is probably due to water in the cables.
Cross connection Direct wiring fault Check for crossed pairs.
Cross-talk Split pair A split pair (a circuit made up of wires from two
separate wire pairs) will be unbalanced and
prone to cross-talk.
Constant ringing Telephone wire in
contact with an AC
power line
This is a potentially hazardous situation!
Remove the test set from the line carefully and
immediately.
Symptom* Possible Cause /
Troubleshooting Step Explanation
*Water may cause most of these symptoms and may cause multiple symptoms to appear at
the same time.
