Battery status indicator
When the transceiver is powered on, the number of bars on the battery status indicator [21] will appear
on the display [1] to show the level of the rechargeable or inserted batteries.
Rechargeable batteries/batteries fully charged
Rechargeable batteries/batteries two-thirds charged
Rechargeable batteries/batteries one-third charged
Rechargeable batteries/batteries empty
When the rechargeable or inserted batteries are exhausted, an acoustic signal will be heard, in which
case replace the batteries or recharge them if using rechargeable batteries.
Advanced operation
The Menu button [5] allows you to customise your PMR. For more information about the functions, see
the following pages.
If no button is pressed for five seconds while changing a setting, the handheld
transceiver will return to idle mode and use the previously adjusted setting.
CTCSS (Continuous Tone Coded Squelch System)/DCS (Digital Coded
Squelch) code
If many handheld transceivers are being used in your vicinity, it is likely that other people will be using the
same channel. To avoid receiving the signals of other parties, CTCSS or DCS codes can be used.
The three-digit CTCSS or DCS code is a tone frequency that the PMR will transmit. Two stations that have
been set to the same channel and the same CTCSS or DCS code can listen to each other. No other
stations will be heard on the same channel, unless these stations use the same CTCSS or DCS code. Your
SilverCrest SPMR 8000 A1 supports 38 analogue CTCSS (1 to 38) and 83 digital DCS (1 to 83) codes.
Any receiver tuned to the same channel and using the same CTCSS or DCS code
can listen to your conversation.
Using a CTCSS or DCS code does not prevent your conversations from being
intercepted by other parties: 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 transmissions on this channel.
