Functional Overview
NG Radios
Radio Operation with KL R off
Operation is possible with the key off on the C53 and CD 53 radios. If the radio is turned
on with KL R off, it will play at the last stored volume and settings for 16 minutes until the
General Module sends the sleep command. No changes may be made to the radio unless
KL R is switched back on. The radio can be turned on and off as many times desired.
Diversity Antenna
Antenna diversity has been adapted to the new generation of radios. When the radio is in
operation, the diversity control unit is activated by the “RAD ON” signal.
World Frequency Radio
Radios on vehicles sold in the U.S. are world radios. Specific country settings can be made
using the service mode. The settings are stored in an EEPROM.
Car Memory
If programmed, when locking the vehicle using the remote transmitter the:
 last station
 Volume setting
 Last audio mode (Tape, FM, CD etc.)
are stored according to the key number used. Unlocking the vehicle with the same
transmitter will restore the settings. There is a maximum setting for volume which may be
lower than the setting when the radio was last operated.
Clock
Time can also be displayed when KL R is off by pressing the clock button on the
Radio/MID.
Backlighting
The LCM/LSZ produces two signals for the control of radio backlighting.
 Hardwired KL 58g
 Lights on/off over the K/I Bus.
The radio contains a photo-cell for adjustment of backlighting to ambient conditions.

Service Mode Functions
1. Serial Number:Display of the radio serial number.
2. Software version:Display of the radio software version. Displayed as (calender week,
year, version)
3. GAL: Speed-sensitive volume control. Can be adjusted from level 1-6 using the 6 pre-
set audio buttons. Vehicles equipped with DSP do not use this feature.
4. Field strength and Quality (F/Q): The station currently displayed can be assessed for
field strength and quality. An “F” (i.e. F15) number is used to indicate the strength of the
signal being received by the radio. This is a good test of the antenna system, station sig-
nal, and the radio itself. A “Q” (i.e. Q-00) number is used to determine the quality of the
radio station including both the audio and RDS signal if applicable.
5. DSP: This function provides information about whether the vehicle is fitted with DSP.
The value is displayed as a one (fitted) or zero (not fitted) and is communicated by the DSP
amplifier via the I/K bus.
6. TP Volume: Provides adjustment for traffic report minimum volume. Not used in the
US.
7. AF: Alternative Frequency tracking setting. Not used in the US.
8. Area: Used to select the appropriate market setting (USA, Canada, Europe, Japan and
Oceania). Adjust using the pre-set buttons.
9.Index: Display of the revision index.
