53SL ES Series Mobile Radio Operating Manual April 2009 3-5
Dual Control Configurations Section 3 - Dual Controls & External Speaker
3.1.6 Master / Slave Programming
In both dual control configurations, either control head can be designated as the Master
and the other as the Slave. The Master control head controls the volume of its internal
speaker and any external speakers that are connected to the radio's 8-pin accessory
connector (see installation manual for connection details).
All 53SL ES mobiles ship from the factory with the dash-mount control head and any
remote control heads set as Master, so in all dual-control configurations, one control head
must be set as the Slave to ensure correct operation.
Control head addressing is set as follows:
1
Power up the mobile radio
2
Press buttons F3, F4 and F5 at the same time, and release (see Figure 3.4).
3
The display will read "ADDRESS 21" if the control head is configured as the Master,
or "ADDRESS 22" thru "ADDRESS 27" if the control head is configured as the Slave.
4
Rotate the Select knob to select the appropriate address.
5
After a short time-out period, display will read "CYCLE PWR"
6
Power the radio off and back on, and the configuration will be updated.
