GENERAL
-General handling
PDA-module GP-1, SIM-Flex GEM-1 and PDA-LCD are the same for all products.
CMT-module GE-8s ( MCM1 code 0200725 ) and User Interface-module GK-2 are meant for RAE-1/I,
while GE-9s ( MCM1 code 0200865 ) and UI-module GK-2-1 are meant for RAK-1/I.
To find out a failure easier, interchange separate modules with some which are working proper,
so that you can define the fault to a single module. Check general every connector for broken
solderings, if bent or soiled.
EMC grounding tape is recommended to replace always with new one after removal.
Take care not to destroy HF-Microphone and Coax-cable when assembling the communicator,
further more it is absolutely necessary to use the right screws at their intended places!
-Component characteristics:
Some components contain important data.
Several described steps are only practicable if you are able to reflash/ realign the phone and/or rewrite
IMEI/SIMlock in certain cases. Please pay attention to separate notes.
-Realign after repair
Characteristics of replacement parts are different.
To prevent additional faults after repair (eg. low standby time, loosing network etc…) it is necessary
to retune phone values after repair.

HARDWARE CHANGES RAE-1 / RAK-1
SB 010 / RAE-1
STRANGE CHARACTERS ON THE DISPLAY
In some communicators the phone display (LCD) becomes scrambled if the user has pressed e.g. 2-5-8-0 keys of
the phone’s keypad very quickly. Typically there will be additional, missing or odd pixels at the top of the field
strength or battery level bars. To prevent these strange characters to appear at the display, the value of C346 has
been changed from 100 pF to 47 pF (On GE8 module).
SB 015 / RAE-1 SB 004 / RAK-1
NEW REED RELAY S170
This new relay is more reliable and sensitive than the old one. Change if display message “PLEASE CLOSE COVER”
appears while cover is fully closed.
This modified relay was used in production from IMEI number 490169/10/041518/0.
SB 017
NEW HARDWARE VERSIONS 5.0 AND 5.1
To improve phone’s LCD functionality and for better PDA-performance, several changes have been done,
for details see Service Bulletin 017

USER INTERFACE PROBLEMS
Check all connectors and flexfoils for their condition –if bent, dirty or poor soldered.
Display failures
CMT: Too low or too strong Display contrast or missing segments:
Check for poor soldering and/or mechanical condition of flexfoil
Check if segments missing after fast pressing keypad (eg. keys 2-5-8-0)
If this is the case – change C346 from 100pf to 47 pf
see also Service Bulletin 010 for GE8 Modul
unstable LCD backlight – change PSL N230
PDA: Bad or flickering LCD – Display driver defect – change Display
LCD Contrast problems – check/change R93, R97
Audio failures
Always check GEM-1 SIMFLEX connections / - connectors X001 (UI) and X212 (CMT)
Bad Audio Quality incoming (Xmic) – check Earphone B001 if dirty / change if necessary.
Bad Audio Quality outgoing (MicX) – check Mic B002 for dirt / change if necessary.
Ringing tone problems – check Buzzer B003 if dirty or bend / change if necessary.
Keypad failures
If there are problems with any keypad and/or functionkeys –
Metal key domes are possibly mechanically defect –
disconnect CMT LCD and change GK2 / GK2-1 PCB.
SIM failures
Check mechanical condition of GEM-1 SIMFLEX.
Check connections / -connectors of SIMFLEX.
Check pads of SIMCARD reader X002 if bent.
Change GEM-1 SIMFLEX if necessary.
General start problems
Internal failure respectively Screensaver Error GEOS.ini.
Try to format and make SW – update after formatting.
This can be done with service-software
or by pressing Shift + Esc + F and installing the battery to boot the communicator.
Keep the keys pressed until you get a screen to confirm the formatting.
Note that formatting will remove all user-generated data. You should save user`s data before proceed !

SIMcard. E 400 pulses up VSIM four times
to an amplitude of 5 Volt.
8 (29)
If the phone is switched on with SIMcard Vsim keeps on 5 Volt expected that SIMcard is not dirty or damaged.
Note that SIMClock and SIMData are only
present when SIMcard is active, for
example when phone registers to network.
Some SIMcards do not allow to switch off
SIMClock but the clock-frequency can be
reduced from 3.25MHz to 1.625MHz
if SIMcard is not used.
SIMReset is low-active, that means that
the Simcard will be reseted when SIMReset
is 0 Volt.
This is the case after switching on the
phone. While VSIM is already high,
SIMReset keeps low for a few milliseconds
– in this time the card will be reseted.

SIMflex GEM-1
Check mechanical appearance of flexfoil, change if pads torn off or traces are damaged.
SIMlines faulty
Check connection between
E400 pin 90 and X212 pin 7 (100 Ohm, R331).
E400 pin 91 and X212 pin 9 (100 Ohm, R338).
E400 pin 94 and X212 pin 6 (68 Ohm, R330).
E400 pin 92 and X212 pin 8 (resistance is 1800 Ohm, to ensure functionality check also V330/331! ).
Check resistance of SIMlines to GND at X212, value shouldn’t decrease 100kOhm.
E 400 faulty
If SIMlines keep inactive even though SIMcard is inserted, Sim-Flex is ok, SIMlines
have no shorts to ground and voltage at E400 pin 93 is 4.8 Volt, it is necessary to change E400.
Note that you have to realign phone values after changing E400.
