Channel and Jumper Changes
Opening a Base
As preparation for changing the Channel on a Base Station, the case
must be opened to expose the circuit board with the switches and
jumpers. Be sure you disconnect power before opening the case.
Turn your Base Station upside-down, and unscrew its single phillips
head screw. If you don't completely remove the screw, you can use it as
a lever to pull up on the cover.
Otherwise, insert a fingernail, credit card edge or small screwdriver
blade into the gap between the Base and side of the case, and gently use
it as a lever to lift up the edge of the Base. Then grasp the edge of the
Base and open it outward like a door.
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
The Base Station must have it's channel set to the same channel as the
R/F Terminals in their network. The channel is set on a Base 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.
