Advanced Operation SilverCrest PMR-1200
English 17
6.3 CTCSS/CDCSS code
The 3-digits CTCSS/CDCSS code is a tone frequency that the PMR will transmit. Two
stations that have been set to the same channel and to the same CTCSS/CDCSS code can
listen to each other. No other stations will be heard on the same channel, unless these
stations use the same CTCSS/CDCSS code. The PMR-1200 supports 38 analogue CTCSS
codes (1 to 38) and 83 digital CDCSS codes (39 to 121).
1. Press the button (5) twice. The current CTCSS/CDCSS
code will blink on the display.
2. Press the S or T button to set a different code.
3. Press the PTT button (13) to confirm the setting.
• Any receiver tuned to the same channel and using the same CTCSS/CDCSS
code can listen to your conversation.
• To disable the CTCSS/CDCSS function, select the code “0”.
• Using a CTCSS or CDCSS code does not protect communications from
being intercepted. Any radio transceiver or receiver tuned into the same
channel that is not using a CTCSS or CDCSS code will be able to listen to all
transmission on this channel.
6.4 Monitoring a Channel
You can search the current channel for any weak signals. To do this, use the Channel
monitoring function.
1. Press and hold the
button (9) to enable channel monitoring.
2. Release the
button (9) to stop channel monitoring.
6.5 Baby monitor
You can use your PMR set as a baby monitor. One of the transceivers will transmit a signal
whenever your baby is crying or another noise is detected in the room (VOX). This
transceiver will not receive any signals to avoid disturbing the baby’s sleep.
In order to be able to receive the signal of the baby transmitter, the second PMR must be
tuned to the same channel and the same CTCSS/CDCSS code (see pages 16 and 17).
In baby monitor mode, most transceiver functions are disabled (except button
lock, menu and power off/on). You must exit the baby monitor to gain access to
these functions again.
