1.1 Operating other devices in the same frequency band as the  
CA12CD will reduce user density and range. In North America,  
the CA12CD operates in the UPCS frequency band (1.92 to  
1.93 GHz). In other regions, the CA12CD operates in the DECT  
frequency band (1.88 to 1.90 GHz). Various versions of the  
CA12CD are available for use in specific countries.  
1.2 User density and range can vary widely due to such variables  
as building layout and whether other devices are operating in  
the same frequency band as the CA12CD.  
1.4 Plug the AC Adapter into the wall outlet, and plug the round  
power connector into the back of the Base Unit. The Base  
Power Indicator will illuminate.  
1.5 Slide the Battery Pack onto the Remote Unit. When the  
Battery Pack is installed or changed, the On-Off Indicator will  
begin to flash slowly as soon as the unit is ready for use. This  
may require about 45 seconds while the Remote Unit  
determines and selects the most reliable radio channel.  
1.6 Attach a headset to the Remote Unit.

Setup  
In low-density installations (e.g., 5 units placed 10 feet apart),  
the range can be greater than 100 feet. In high-density  
installations (e.g., 30 units placed 18 inches apart), the range  
could decrease to 10 feet.  
1.7 Place CA12CDs at least 12 inches away from CRT-type  
computer monitors.

2.6 A fully charged Battery Pack will last for up to eight hours.  
2.7 To maximize the life of the Battery Pack, turn the Remote Unit  
off and place it into the charging well when not in use. Prior to  
being used, Battery Packs must be charged for at least one  
hour or until the Charging Indicator changes from blinking to  
continuously on.

2.1 To attach the Battery Pack to the Remote Unit, simply slide  
the Battery Pack onto the Remote Unit and snap it into  
place. Do not force them together.  
2.2 The Base Unit is equipped with two battery-charging wells.  
The larger well allows charging of the battery while it is  
attached to the Remote Unit. The smaller well allows  
charging of a spare Battery Pack all by itself.  
2.3 Insert the Remote Unit and the spare Battery Pack into their  
respective charging wells. The Charging Indicators will flash  
while the Battery Packs are charging.

Note: Always release (disengage) the PTT Button before swapping  
Battery Packs.  
Warning: Touching the battery-charging contacts or placing  
objects other than the Battery Packs and Remote Unit in the  
charging wells may adversely affect the operation of the CA12CD.

3.6 The Base Unit and the Remote Unit are paired with each other  
at the factory in a process called subscription. If you replace  
your Remote Unit, or if your Remote Unit loses its subscrip-  
tion (shown by a rapidly flashing On-Off Indicator), you can  
perform the subscription process as follows:

How to select  
the lockable  
or nonlockable  
switch position  
Operation  
• Hold both of the Talk (Sending) Fine-Adjust Volume  
Controls on the top of the Base Unit down.  
The Base Power Indicator will begin blinking.  
• Hold the Remote Unit’s Listen (Receiving) Fine-Adjust  
Volume Control in either the up or down position.  
The Remote Unit’s On-Off Indicator will turn on steadily  
(no flashing).  
• The Remote Unit will subscribe to the Base Unit, after  
which the Base Power Indicator will return to the steadily  
on state. The Remote Unit’s On-Off Indicator will go out for  
a few seconds and then begin to flash slowly. Your CA12CD  
is now ready to use.

3.1 To maximize user density, always turn the Remote Unit off  
when not in use.  
Lockable Position  
Note that the selector  
slot is aligned vertically.  
The Push-to-Talk Button  
can be depressed  
momentarily or locked  
in the ON position by  
first depressing then  
sliding the button until  
it locks.  
3.2 Press the On-Off Button located on top of the Remote Unit.  
The green On-Off Indicator will begin to flash. If the battery  
has just been installed, the Remote Unit will automatically  
turn on and the On-Off Indicator will begin to flash. This  
may require about 45 seconds. (Reference Section 1.5)  
3.3 Depressing the Push-To-Talk (PTT) Button on the Remote  
Unit will generate the “key” signal to your console or radio.  
While the PTT Button is depressed, the green Talk Indicator  
on the Base Unit will illuminate.  
Nonlockable Position  
Turn the selector  
horizontally. The Push-  
to-Talk Button can be  
depressed momentarily  
when you wish to speak.  
3.4 The operation of the PTT Button can be adjusted with a  
screwdriver to be either lockable or non-lockable as shown.  
3.5 To get the best audio performance from your CA12CD, please  
use the guidelines on the separate card, Setting Model CA12CD  
Audio Levels. Properly-adjusted audio levels are especially  
important for avoiding sidetone echo, as well as for being able  
to hear your callers and be heard clearly by them.
