Changing Channels
To change to another channel, simply press the [CH] key followed by the number of the required channel within
two seconds.
For example: To select Channel 8, press [CH] [0] [8]
To select Channel 99, press [CH] [9] [9]
Note that it is always necessary to enter two digits for the Channel Number. The channel # location displayed in
the LCD will become blank as soon as the [CH] key is pressed. The cursor will blink at the location of the
channel number, and display the new numbers as they are entered.
It is also possible to change channels by using the [CH], [A] and [B] keys instead of entering the channel
numbers. Pressing the[CH] then the [A] key will advance the channel to the next higher programmed channel,
while pressing [B] will advance the channel to the next lower programmed channel.
Note that this action will ignore channels that have not been programmed into the Base Tech II Base Repeater.
Accordingly, the LCD display may appear to advance more than one channel if the missed channel is not
programmed into the Base Tech II Base Repeater.
Signaling
The Base Tech II Base Repeater includes some very sophisticated signaling capabilities. We suggest that you
have your radio supplier conduct some training on the use of these capabilities prior to using them.
While it is possible to use these signaling capabilities in both repeater mode, and in base station mode, many
will only be useful in practice when the Base Tech II Base Repeater is used in base station configuration.
The Base Tech II Base Repeater supports the 5-Tone sequential, and/or the DTMF, and the Single Tone
signaling formats. The required signaling format(s) must be enabled when the Base Tech II Base Repeater is
programmed.
5-Tone Signaling
Available Tones
5-Tone signaling is commonly referred to as “Selective Calling” (or Selcall) and usually comprises of a series of
5 tones sequentially transmitted or received in accordance with certain international standards. It is possible to
use longer sequences to enhance the signaling capabilities and to provide additional functions.
Accordingly, the Base Tech II Base Repeater will encode up to sixteen (16) tones and decode up to eight (8)
tones.
These tones can be any of the following letter/number combinations:
[0] - [9], and [A] - [D]
The most recently entered tone can be recalled and deleted by pressing the [
] key repeatedly.
