CODING RADIO - AR82.60-P-7502-01A
1. If the radio is disconnected from the power supply, it is not operational when re-connected. After
switching on the ignition and the radio, the readout CODE appears in the display.
2. The code number for the radio is advised to you on the enclosed CODE CARD.
3. To enter the first digit of the code number, you have to continue pressing station button 1 until the correct
digit appears in the display. Adopt the same procedure for the second, third and fourth digits.
4. Once you have entered the correct code number with the station buttons 1, 2, 3, 4 and confirmed the entry
with the SEEK button (press down), the readout CODE disappears. The radio can now be operated.
5. If you enter a wrong code three times, you must wait 15 minutes before making a new entry. In addition,
if 9 incorrect entries are made, the radio will then not operate for 24 hours. During this time the radio and
the ignition (terminal 15) must remain switched on.
CODING RADIO - AR82.60-P-7502-01B
1. If the radio is disconnected from the power supply, it cannot be operated by simply reconnecting. After
switching on the ignition and the radio the word "CODE" appears in the display on the radio.
2. The code number for the radio is given on the enclosed CODE CARD.
3. Enter the code number with the station button, e.g. number 1, station button 1.
After entering the first number the word "CODE" disappears and the number entered appears followed
by 4 dashes. The next character to be entered flashes. After entering all five numbers, the first character

starts flashing again. In this state the code number can be written over as frequently as desired. A
correction can be made only by entering the complete code number again.
4. Confirm code number:
Press TUNE, AUTO/SEEK or SC button. The radio automatically switches on and indicates the radio
station or frequency stored with station button 1.
5. If an incorrect code number is entered and confirmed, the word "CODE" appears again on the display. If
an incorrect code is entered three times the word "WAIT" appears on the display and the radio locks up
for approx. 10 min. If the code is entered incorrectly three times again the radio locks up again for 10
min. Three more incorrect entries (a total of 9 incorrect attempts) increase the lock-up time to 60 min.
Another three incorrect entries lock up the radio for another 60 min.
The waiting time runs only when the radio is switched on.
CODING RADIO - AR82.60-P-7502-01GH

2. The code number for this radio is given on the included code card.
3. Enter the code number with the station buttons, e.g. number 1 = station button 1..
4. After entering the first digit the word "CODE" disappears and the number entered is displayed followed
by four dashes. Enter the next numbers with the corresponding station buttons. After entering the five
digit code number compare the code number with the number on the display. At this point the code

ahead or to turn min. 60°.
This only increases the

completed when the location
is indicated in the AUDIO

General

A periodic process with a period of high

accuracy is required to measure time (clock)

(e.g. rotation of the earth, pendulum

oscillation.)

Electronic clock

Accordingly an electrical clock signal of high

frequency accuracy is required for an

electronic clock. This clock signal is usually

derived from the very constant mechanical

oscillations of an oscillator crystal. A quartz

(q) with a really high frequency

(e.g. f
1
= 1 MHz) is normally used. This

frequency is then adjusted down to the

required frequency f
2
1 Hz or 1/60 Hz by an

electronic frequency divider (t), i.e. one pulse
is generated every second or minute. The

display unit can be actuated by this pulse. A

stepper motor (s) is used on clocks with a

pointer and a liquid crystal display (I) on

clocks with a digital display.

With an additional circuit (b) the clock can be adjusted via control

buttons.
In addition the time or a time/date pulse is also made available to

other systems (e.g. trip computer, Active Service System (ASSYST),

maintenance display).

PROGRAMMING
RECODING RADIO
1. Turn ignition on. Ensure CODE is displayed on radio display. Enter code numbers using radio station
buttons. For example, use station button No. 1 for code No. 1 and so on.
2. After first number is entered, CODE disappears and number entered is displayed followed by 4 dashes.
After entering 5-digits, confirm correct security code has been entered. If incorrect code has been entered,
entire code must be reentered.
3. Confirm entry of correct security code using "<" (less than) or ">" (more than) buttons. If an incorrect
code is entered, CODE will be displayed on radio display. If security code is entered incorrectly 3 times,
WAIT will be displayed and radio will be disabled for about 10 minutes.
4. If, after 3 more attempts, correct security code has not been entered, radio will be disabled for 60 minutes.
Radio disable time runs down only when radio is turned off.
VERSION CODING
Version coding is performed using a Mercedes-Benz Hand-Held Tester (HHT) and is on-screen menu guided.
After connecting HHT to DLC, vehicle communication is possible as soon as ignition key is inserted into
ignition switch (position of switch does not matter). Version coding menu, position 1, is reached via main menu
and control module adaptation, position 5. There are 2 possible version codings available: readout of version
code and transfer to new control module or readout of version code and to alter code.
To access A/C system version coding, position 2 must be selected and then position 7 for A/C system. Two
selections can be used: A/C system is installed or A/C system is not installed.
SELF-DIAGNOSTICS
RETRIEVING & ERASING DIAGNOSTIC TROUBLE CODES
Retrieving and erasing of Diagnostic Trouble Codes (DTC) must be performed using Mercedes-Benz Hand-
Held Tester (HHT). See HHT instructions for retrieving A/C-heater system related DTC. After noting codes,
see CLIMATE CONTROL DTC
table. To erase DTC, follow HHT instructions.
When retrieving DTC from A/C push button control module, short and open circuits cannot be differentiated
from each other in every instance. When accessing DTC from any control module memory, all stored DTC are
shown. As a result, some DTC shown will not appl
y to climate control system. CAUTION: Before disconnecting battery, obtain 5-digit radio security code from
vehicle owner. Radio will be disabled until properly recoded.
NOTE: Radio will not operate if power supply to radio is interrupted. Obtain 5-digit
radio security code from vehicle owner before disconnecting battery.
