USER GUIDE
– CM21-CM22 STEERING WHEEL SWITCH
Our CM21 and CM22 Steering Wheel switches are visually similar and operate in the
same manner, but are technically different. The CM21 is and IR type and has a
purple receiver disc mounted (normally on the dashboard) behind the rear of the
switch. The CM22 is an RF type and does not have the purple receiver disc.
LED INDICATOR FUNCTIONS
There are 2 LED lights, one on the switch body below the ON/OFF button, and the
other mounted on the vehicle dashboard, with a black disc displaying the word
CRUISE. On the CM21 the only time this LED will illuminate is after years of service
and is a notification that the battery in the switch is losing voltage and should be
changed. On the CM22 this LED will illuminate whenever a control button is
pressed, and will display groups of 5 flashes with no button use when battery should
be changed.
The battery type is a popular long-life CR2032 type, and should last for several years
in normal operation. It should be replaced without delay when the LED signal is
shown, as the Cruise Control will cease to operate when the battery has lost charge.
The DASHBOARD LED is the Cruise Control status indicator. It will display a dull
pink colour when switched OFF to assist in locating the LED. When the Cruise
Control is switched ON (but not engaged) the LED will display a Green colour, when
ENGAGED it will display an Orange colour.
ON/OFF BUTTON
This button turns the Cruise Control ON or OFF. Status LED will change colour as
detailed above.
SET/ACC BUTTON (Set/Accelerate Functions)
This button has 2 functions. When the Cruise Control is in standby (Green LED)
pressing this button will SET (engage) the Cruise Control at your current speed.
When the Cruise Control is engaged (Orange LED) pressing this button will
ACCELERATE (increase) the speed. One brief press will increase speed by 1kph.
On AP300 and AP500 models
pressing and holding the button will increase speed
in a gentle and progressive manner, holding the higher speed when the button is
released.
On AP900 and AP900C models
pressing and holding the button for approx 1.5-2
seconds will increase speed by 10kph above current set speed. This is indicated by
2 brief beep tones when holding the SET/ACC button for the required period.
