BASE UNIT SECTION
1.
Overview
By operating
the connecting
IC401 pin23 and groung,
and PAGE SW on the base, pass/fail
of the completion
process can be
determined
through the status of the LEDs, operation
of the device, etc.
2.
Switchover
of the Usual Mode and the Test Mode
After Test mode, RAM DATA will be Initialized.
(1) Switchover
by operation
of Microcomputer
ports
This way, the microcomputer
ports, P42 (17pin) and P43 (18pin), are used, and the switchover
(Test mode and Usual Mode) can
be performed
anytime.

(2) Switchover
by operation of Power ON
When power on, connect IC401 pin23 and ground , and keep pressing the PAGE key.
Then disconnect
IC401 pin23 and ground, and the PAGE key keep off.
Test mode will be Remote Unit Call Status.
In case of Test mode in this way, to switchover the usual mode is either one of the following ways.
1.
detect charge
2.
turn off the power, retry
3.
Types of test modes
Test mode has the following
3 states. Description

PLL Channel setting
How to set up PLL Channel below.
Range of channel is 1 to 10 ch for both TX and RX.
When setting the channel, IN USE LED put out 40msec.
(1) When power on, both Tx and Rx Channel are setting 10 ch.
(2) Press the PAGE key, both Tx and Rx Channel are setting 7 ch.
Moreover,
RX MUTE will be on.
(3) Next
pressing
the PAGE key, both Tx and Rx Channel are setting 2ch.
(4) Next pressing the PAGE key, both Tx and Rx Channels are setting 1 ch.
(5) Since pressing the PAGE key, both Tx and Rx Channels change as below.
