3-1. Outline

The transceiver can be

modified

to

have

the

emer-

gency

mode and

installed

in the car.

lf

the driver

(such

as a taxi driver) encounters a

robber, he

can transmit

an

emergency signal to a base station

automatically by

treading

on the foot switch installed on the

floor of

the

car.

The emergency mode can be activated

when

the

power

switch is turned off by changing the

power

switch

function

to the LCD display ONiOFF

switch

function.

An external speaker

may

be sounded or

lights may

be

flashed in emergency to warn robbers by modifying

the option

KAP-I

to

the Horn/Light

drive

relay output

circuit and

installing it in

the transceiver.
