AL2430-2PH Function Description

The versatile AL-PH Microphone performs the functions of a wireless microphone and a system remote control. It can be used as

a Handheld Microphone, a Lapel Microhone with included Lanyard(AL-LANYARD), or a Belt Pack Microphone with optional AL-HSM

headset. Each AL-PH has a switch located under the battery door used to set its IR Channel to either A or B. One AL-PH must be set

to Channel A and the other AL-PH must be set to Channel B. The system will not function properly if there are two AL-PHs set to the

same IR channel.

Also located under the battery door is the LOCKOUT switch. When this is engaged all function buttons are disabled and the unit can be

used as a microphone only.

The AL-PH can be set in two different modes that effect the control it has over the AL2430 system.

Mode 1:

• The right side blue LED will be illuminated

• Volume UP / DOWN buttons will control the microphone volume

• The Mute button mutes the microphone

Mode 2:

• Both blue LEDs will be illuminated

• Volume UP / DOWN buttons will control the multimedia inputs on the AL2430 Receiver / Amplifier

• Mute button will mute the multimedia inputs on the AL2430 Receiver / Amplifier

Power and Panic buttons function as described below regardless of microphones mode setting.

The Power button needs to be pressed for three seconds to turn the unit on or off.

When the Panic button is pressed along with the Mode button, a signal is sent to the AL2430 Receiver / Amplifier. This closes its Panic

Output relay. The Panic Output relay can be connected to an external system. For example: the school's Paging / Intercom system to

alert someone of an event in the class room that requires immediate attention.

Using the Remote Control 51

Replacing the Batteries

The remote control uses two AA alkaline batteries. Follow these steps

when you need to replace them:

1. Press in the tab to remove the battery cover.

2. Remove the old batteries, then insert the new ones as shown.

3. Replace the battery cover. (It should click into place.)

caution

When replacing batteries,

take the following

precautions:

■Replace the batteries as

soon as they run out. If a

battery leaks, wipe away

battery fluid with a soft

cloth. If fluid gets on your

hands, wash them

immediately.

■Do not expose batteries to

heat or flame.

■Dispose of used batteries

according to local

regulations.

■Remove the batteries if

you won’t be using the

remote control for a long

period of time.

note

The remote control

automatically shuts off when

it detects a button being

pressed more than

30 seconds. This conserves

battery life. It can be

helpful, for example, when

the remote is in a carrying

case and the PPower

button is accidentally

pushed.

50 Using the Remote Control

■Zoom

Displays images using the full width of the projection area and

maintains the aspect ratio of the image. 4:3 ratio images are cut

off on the top and bottom.

■Full

Displays images using the full width of the projection area, but

does not retain the aspect ratio. 4:3 ratio images are elongated

horizontally.

■Through

Displays images as is (aspect ratio and resolution are maintained).

Black bands appear if the resolution is 1280 × 800 or less; images

are cut off if the resolution is over 1280 × 800.

Press the Aspect button repeatedly to cycle through the available

options.

You can also change the aspect ratio using the projector’s Signal

menu. See page 58 for details.

Using the Remote Control 49

Zooming Your Image

Follow these steps to zoom in on a portion of the image:

1. Press the E-Zoom + button on the remote control.

You see a crosshair indicating the center of the zoom-in area.

2. Use the four “arrow” buttons on the remote control to position

the crosshair in the area you want to enlarge.

3. Continue pressing the E-Zoom + button to enlarge the selected

area up to 4 times.

4. While the image is enlarged, you can:

■Use the arrow buttons to pan about.

■Press the E-Zoom – button to zoom out.

5. When you’re done, press the ESC button to return to the original

size.

Changing the Image’s Aspect Ratio

You can use the Aspect button on the remote control to change the

aspect (width to height) ratio, depending on the input signal.

■Auto (video images only)

Automatically sets the aspect ratio according to the input signal.

4:3 ratio images display at 4:3, squeeze-recorded signals display at

16:9, and letterbox signals display at Zoom ratio (described

below).

■Normal

Displays images using the full projection area and maintains the

aspect ratio of the image. 4:3 ratio images project with black

bands on the sides, 16:9 images project with black bands on the

top and bottom, and 16:10 images use the entire projection area.

■16:9

Converts the aspect ratio of the image to 16:9. 4:3 ratio images

are elongated horizontally to fit.

48 Using the Remote Control

Turning Off the Picture and Sound

Press the A/V Mute button on the remote control to turn off the

image and sound and darken your screen. This is useful if you want to

temporarily re-direct your audience’s attention without the distraction

of a bright screen.

To turn off the picture and sound, press the A/V Mute button. The

screen goes dark.

To turn the image and sound back on, press the button again.

You can create an image, such as a company logo or a picture, to

display on the screen whenever you press the A/V Mute button. See

page 67 for more information.

Stopping Action

Press the Freeze button to stop the action in your video or computer

image and keep the current image on the screen. The sound will

continue, however. Also, because the source continues to transmit

signals, you won’t resume the action from the point you paused it.

To restart the action, press the Freeze button again.
