The module jig MJS-4 is used for RAE-5 module testing and repairing. There
are slots for each module in the jig. The jig includes connections for charger,
power supply, external RF, audios and FBUS/MBUS. Slots for Memory card and
SIM card are also included. This equipment is powered by a laboratory power
source.

Warnings:
Power Source
Do not connect negative voltage to Voltage IN -terminals.
Do not connect voltages over 4,2 volts to Voltage IN -terminals.
Flash Mode vs. EPOC Running -mode
If you are using Wintesla service software (for flashing or for testing) do not use
the ”Run EPOC” switch. EPOC software is not allowed to be running during
flashing or while software resets are possible (Wintesla connected).
External Connections
6. Service Tools
RF
For external RF connection there is a SMA jack connector. The connection is
defined to be made with service cable XRF-1.
Attenuation of the RF connection (without XRF-1 cable) is
appx. 0,2dB for 900MHz band and
0,4dB for 1800MHz band.
System Signals
For system signal connection (Fbus/Mbus) there is a modular 10 socket in the
jig.
The socket is compatible also with modular 8 plug.
Preferred cables for system connection are XCS-4 and DAU-9S.
Audio Signals
For audio signals the jig includes also a modular 10 socket. SGND is separated
from general GND although in ADS-1 service cable specificed for use with the
jig those are short-circuited.
Input Terminals
For powering the jig there are two ”banana” sockets. Red one for + terminal
and black for GND terminal.
Detection Switches
There are three switches by which different detections can be done. Switches
are press switch type so the connection is made only while the switch is
pressed.

Starting
Open the cover of the jig and place SIM card and microphone to their places if
needed.
Then place modules of RAE-5 to proper positions: first KL8 then in order JC4
(board to board adapter), UL8 (keymat on it if needed) and (keymat under if
needed) DL1. Give special attention to connections of board to board connectors, connectors are not specified for continuous removing.
Close the cover of the jig.
Turn the jig over.
Connect the flex to UI module.
Place memory card and/or audio holder under its/their covers.

2S102: Hook detection
3S103: Accessory detection
Connect the necessary cables. Jig is ready for use.
Power ON
There are two working modes in jig:
Default State
Entering to default state does not require any user actions. Just turn the power
of the source ON. Symbian software will not run. There is a notification about
the state in PDA display. Wintesla service software can be used with jig, different kind of test cases will work (PDA display test, MMC test, etc.).
EPOC Running State
”Run Symbian” switch is needed to be pressed down while turning the power
ON. The switch can be released after the SW has started to boot up. EPOC
software will now run.
In Use
For simulation of cover open / cover closed there is a magnet toggle on cover
of the jig. Sticker beside the toggle describes the meaning of positions. The
magnetic force (field strength) is a bit weaker than in Linda communicator.
There are extra GNDs included to jc4 board to board adapter. There is also a
special GND pin in middle of the jig.
Finishing
Before turning the main source off press the nail in audio cover to make an interrupt to processor. This is important especially if you have an active call ON
