1.3 General Safety Information

1.3.1 Portable Operation

• DO NOT hold the radio so that the antenna is very close to, or touching, exposed parts of the body,

especially the face or eyes whilst transmitting. The radio will perform best if it is held in the same
manner as you would hold a ‘land’ telephone handset, with the antenna angled up and over your
shoulder.

• DO NOT operate the portable phone in an aircraft. Switch off your telephone. The use of a cellular

telephone in an aircraft may be dangerous to the operation of the aircraft, disruption of the Cellular
Network may occur, and is illegal. Failure to observe this instruction may lead to a suspension or
denial of Cellular Telephone Service to the offender, or legal action, or both.

1.3.2 Mobile/Portable Operation - Telephone use in Vehicles:

• All equipment must be properly grounded according to installation instructions for safe operation.

• Users are advised to turn off their equipment when at a refueling point.

• Safety is every driver’s responsibility. Cellular telephones should only be used in situations in

which the driver considers it safe to do so.

1.3.3 General

• DO NOT allow children to play with any radio equipment containing a transmitter.

• DO NOT operate this equipment near electrical blasting caps or in an explosive atmosphere.

Mobile Telephones are, under certain conditions, capable of interfering with blasting operations.
When you are in the vicinity of such work, look out for and observe signs cautioning against
mobile radio transmission. If transmission is prohibited, you must turn off your mobile telephone
to prevent any transmission.
In standby mode the mobile telephone will automatically transmit to acknowledge a call if it is not
turned off.

• Refer to the appropriate section of the product user manual for additional pertinent safety

information

• All equipment should be serviced only by a Motorola qualified technician.

2.2 M3682 Overview

The M3682 is marketed as a ‘price beater’ unit in its class. It is now designed with a new chip
set to allow the unit to operate at a lower working voltage and therefore prolong battery life, in
both Standby and Talk time.
It is a single band PCS 1900 band product, using the same batteries and rear door as the D520.

Display – 2 X 12 character based LCD display

The M3682 main features include:

• Single Band

• Longer Talk time / Standby time

• Class II Sim tool kit

• Internal headset socket

• Potential to support Enhanced Full Rate mode of transmission (dependant on Network)

The M3682 is mechanically very similar to the D520 (shown beloe); it does however contain the
internal headset socket.

All the circuitry is contained on 1 PCB including the Keypad. The Display is connected to the PCB via
a ZIF connector.
The charger is now placed on the bottom left hand side of the unit
The Antenna is a fixed stub type antenna.

5.1 Manual Test Mode

The GSM Motorola M3682 is equipped with a manual test mode capability. This capability allows
service personnel to take control of the unit, and by entering certain keypad commands, make the unit
performs desired functions.

To enter the manual test command mode, a GSM / DCS test sim (Part No 8102430Z04) must be used.
The test sim is inserted into the SIM slot beneath the battery (See figure 6.1), the battery should then
be re-inserted and the unit powered on. The # button should then be pressed for approximatly 3
second until ‘test’ appears on the display, and the correct commands must then be followed.

SIM CARD

Figure 6.1 SIM Card insertion

5.2 Live Sim Card

A SIM (Subscriber Identity module) card will be required to access the existing local GSM / DCS
cellular network, or remote networks when travelling. (If the roaming agreement has been made with
the provider.)
The SIM card contains all the data necessary to access GSM services, and also:

• The ability to store user information such as phone numbers etc…

• All information required by the network provider to provide use to the network

5.3 Personality Transfer

5.3.1 Introduction

Personality Transfers are required when a phone is Express Exchanged or when the main board is
replaced. The reason for personality transfers are to reproduce the customer’s original personalized
details such as menu and stored memory such as phone books etc… or even just to program a unit with
basic user information such as language selection. There are two possible methods of transferring this
information from unit to unit, or with a master transfer, card to unit: -

• Normal Transfer is used when the customer’s original unit still powers up and as discussed above
the customers personalized menu selections etc… are required to be transferred to the replacement unit.

• Master Transfer is used when the faulty unit will not power up and the transfer is used to configure
the replacement board to a set standard.

Below is the procedure to set up a Master Transfer Card and to carry out each method of transfer
correctly.

5.3.2 Normal Transfer

1. Insert transfer card into ‘Donor’ Unit. Turn unit on till ‘Clone’ appears.

2. Enter 021# to upload first block of data. ‘Please wait’ will be displayed..

3. Remove card.

Note: To test the PCB on its own without a housing or SIM card the unit must first be put into test mode
and then into Tx or Rx mode using the applicable manual test commands. Ensure that a battery is

installed during this, since the battery acts as a SIM card presence detect for the unit. The PCB can then
be taken out of the housing for any analysis.

6.6 Testing on Go / NoGo tester

The set up for the GO / NOGO tester must be set up as shown above. The tester must be set up following
GSM specifications. Note, the D520 is shown in the illustration.
The test incorporates the basic live call, during which many of the RF parameters are checked. This test
can be run in ‘Autotest’ mode, where the radio is classified at the end of the test as a Pass or Fail. This
can be used to indicate whether or not a unit is performing to spec through the accessory connector only.
