USER GUIDE

REMOTE UNIT 

BASE UNIT

1.1  Plug the modular connector on the Console Interface Cable into 

the modular jack on the back of the Base. Plug the other end into 
your console.

1.2  Plug the AC adapter into a wall outlet, and plug 

the power connector into the back of the Base. 
The Base Power LED will turn on.

1.3  Slide the battery pack onto the Remote and snap 

it into place without forcing it. The CA12CD-S will 
take a few seconds to select the most reliable 
radio channel, and then it will start to blink its 
Audio Link LED at once per second, to indicate 
that it is ready to use.

1.4  For first-time use, press the Audio Link button to 

turn the audio link off, and place the Remote into 
its charging well to charge the attached battery 
pack.

1.5  Place the spare battery pack into its charging well.
1.6  The Charge LEDs will flash until the battery packs 

are fully charged, at which time the LEDs will 
stop flashing and remain on. (It is okay to use the 
Remote after only one hour of charging time if 
desired.)

1.7  Press the PTT Button on the Remote to key up your 

communications radio. The Talk LED on the Base will turn on 
whenever the PTT button is pressed. 

Locking Operation
When the selector’s slot is aligned with the Remote’s center-
line, the PTT button can be depressed momentarily or locked 
in the ON position by first depressing then sliding the button 
down toward the selector until the button locks into place.

Momentary Operation 
Turning the selector 90 degrees from the locking position will 
set the PTT button for momentary operation.

2.1  Careful setting of the audio levels, both in your communications 

console and in the CA12CD-S, is essential for getting good audio 
quality and avoiding echo. Please see the separate sheet, Audio 
Settings Guide for the CA12CD-S, for detailed advice.

2.2 Operating other radio devices, such as DECT cordless handsets, 

in the same frequency band as the CA12CD-S will reduce the 
number of units that can be operated at one time, along with 
reducing their maximum range. In North America, the CA12CD-S 
operates in the UPCS frequency band (1.92 to 1.93 GHz). In other 
regions (e.g., the European Union), the CA12CD-S operates in the 
DECT frequency band (1.88 to 1.90 GHz). 

2.3 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-S.

 

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 as little as 10 feet. In general, it is best to place them as far 
apart from each other as possible.

2.4 Keep cell phones at least 3 feet from both the Base and the 

Remote when the Remote is not near the Base. When the Base 
and Remote are near each other, cell phones can be closer than 
3 feet, but should never be placed right next to the Base or 
Remote.

2.5 Remove the battery pack and power cord from any unused units 

to allow more radio spectrum for active units. This is especially 
important where large numbers of them are in use.

 

3.1  A new, fully charged battery pack will last for about 8 hours, 

however, we recommend swapping the Remote’s battery pack 
with a freshly charged battery pack from the Spare Charger 
about every 4 hours. Doing so will help insure that mission-
critical communications are not interrupted by low batteries. 
Following this recommendation will also maximize the battery’s 
service life.

3.2 Between battery swaps, we recommend placing the Remote in 

its charging well whenever possible, and, if it is not being used, 
turning the audio link off by pressing the Audio Link button.

3.3 If the Remote is left in the charging well with the link up,  a new 

charging cycle will typically begin about 3 hours after the first 
charging cycle. Using the Remote at this time without installing 
a freshly charged battery pack could result in reduced talk time.

3.4 A completely depleted battery pack requires about 4 hours to 

fully charge.

3.5 The Remote will continue to draw a small amount of power 

from the battery even after being turned off. If you need to 
store the Remote, remove the battery pack so that it does not 
become completely discharged while in storage. 

Warning: Touching the battery-charging contacts or placing objects 
other than the battery packs and Remote in the charging wells may 
adversely affect the operation of the CA12CD-S. 

Note 3.1: Rechargeable batteries of all types gradually age and lose 
their ability to give and receive charge. Over time, this will result 
in gradually decreasing talk times. In a typical 24/7 operation, 
where the batteries are regularly being charged and discharged, we 
recommend that you monitor their performance and replace them 
as needed.

The Base and the Remote are paired with each other at the factory 
in a process called subscription. If you replace either one, you can 
subscribe them as follows:
4.1  Press and hold the Subscription button on the back of the 

Base. (Alternatively, you can hold both of the Talk Volume 
buttons on the top of the Base down.)

 

a. The Base Power LED will begin blinking.

4.2 Hold the Remote’s Listen Volume Control in either the up or 

down position.

 

a.  The Remote’s Audio Link LED will turn on steadily (no 

flashing). The Remote will subscribe to the Base, after which 
the Base Power LED will return to the steadily-on state. The 
Remote’s Audio Link LED will go out for a few seconds and 
then begin to flash once per second, indicating that your 
CA12CD-S is now ready to use.
