Channel Changes
To determine the current channel of a Base Station , power up the Base and watch the LED light on the front
of the unit. On power UP, a Base LED will blink "channel +3" times. For example, a unit that blinks 5 times
on power up is operating on channel 2. Channel 0 blinks 3 times, channel 5 blinks 8 times.
Changing the Channel on a Base/Relay
The Base Station and its related Relays must have their channel set to the same channel as the RF Terminals
in their network. The channel is set on a Base or Relay by turning a rotary switch to the setting 0-5 (6
different channels to choose from). Use a very small flat head screwdriver to turn the switch to the desired
number. See the circuit board diagram on page A-1 for location of the rotary switch.
Setting the Relay ID
Each Relay must also have a unique ID, which is set by the RF Terminal Serial Configuration Utility.
