7.5 Adjustment Mode
NOTE:
See section 7.2.1 for a list of the equipment and setup procedures required to perform the following adjustment and
calibration procedures.
The following procedures MUST be performed after replacement or repair of one or both of the PCBs in the
handheld unit. Failure to do so may result in incorrect operation of the telephone.
The following adjustments MUST be made on BOARD PAIRS.
There are four distinct calibration procedures to adjust RF performance. These procedures are:
1.
Ramping gain (Section 7.5.1)
2. RSSI (Section 7.5.2)
3. I and Q values (Section 7.5.3)
The adjustment data selected during calibration is stored in the telephone EEPROM.
NOTE:
As G600 has two battery types available, Lithium Ion and Nickel Metal Hydride, all calibration procedures must be
carried out for each battery type.
