Warnings:
High Voltage
There is a 1kV high voltage solder point beside left upper corner of PDA display.
Keep the cover always on the dangerous area unless measuring under the PWB.
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 flash-
ing or while software resets are possible (Wintesla connected).
External Connections
RF
For external RF connection there is a SMA jack connector. The connection is de-
fined 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.
