General Information About Testing

Phone operating modes

There are three different modes for testing/repairing the phone. Modes can be selected

with suitable resistors connected to BSI- and BTEMP- lines as follows:

The MCU software automatically enters local or test mode at start-up if corresponding

resistors are connected.

Note! Baseband doesn't wake up automatically when the battery voltage is connected (normal mode).

Power can be switched on by

• pressing the PWR key

• connecting a charger

• RC-alarm function

In the local and test modes, the baseband can be controlled through MBUS or FBUS

(FBUS is recommended) connections by Phoenix service software.

RF Module

Requirements

The RH-10 RF module supports CDMA800 and AMPS as described in:

• IS2000-2-A Physical Layer Standard for cdma2000 Spread Spectrum Systems; and

• IS-98D (Draft 4) Recommended Minimum Performance Standard for Spread Spectrum

Mobile Stations.

Temperature Conditions

Surface temperature (SPR5 - Product Safety)

Maximum temperature rise is 50

C for nonmetallic surfaces and 30

C for metal sur-

faces at room temperature.
