13.3. X801 (Base Unit), X201 (Handset) Check
Equipment: Frequency counter
Check Point for measurement: BCK
Checking tolerance: 13.824MHz ± 100Hz
13.3.1. Check and Adjust X801 (Base Unit) Frequency
1. Set up Base Unit in TEST mode.
2. Press following keys in order to Adjust Crystal mode. [INTERCOM], [INTERCOM], [INTERCOM], [1] or [2], [2], [2], [1]
* Check BCK frequency.
3. If the BCK frequency is out of the checking tolerance (± 100Hz), adjust to Adjustment tolelance (± 30Hz) by pressing [ ] or [ ]
key.
Adjustment Tolerance: 13.824MHz ± 30Hz
4. Press [INTERCOM] key to write the new frequency factor in Memory.
5. Turn the power off. Then this value is available.
Cross Reference:
TX Burst Mode and Adjust X’tal Mode
(P.46)
13.3.2. Check and Adjust X201 (Handset) Frequency
1. Set DC power supply to 3.9V.
2. Set up Handset in TEST mode (Adjustment flow).
3. Press [1] key to Adjust Crystal mode. (“Clock Adj” is displayed on LCD)
* Check BCK frequency.
4. If the BCK frequency is out of the checking tolerance (± 100Hz), adjust to Adjustment tolelance (± 30Hz) by pressing [ ] or [ ]
key.
Adjustment Tolerance: 13.824MHz ± 30Hz
5. Press [TALK] key to write the new frequency factor in EEPROM.
6. Turn the power off. Then this value is available.
Cross Reference:
Adjustment flow (X’tal mode and Batt Low mode)
(P.52)
13.4. Adjust Battery Low Detector Voltage (Handset)
After handset´s DSP (IC201) or EEPROM (IC202) replacement (*1), Re-writing Battery Low voltage to EEPROM is required.
Follow
Test Mode Flow Chart for Handset
(P.49).
DC power supply and DC voltmeter require the adjustment below.
1. Set DC power supply to 3.9V.
2. Set up handset in test mode (Adjustment flow).
3. Press [1] key and [OFF] key twice to Adjust Batt Low mode. ("Bat Adj" is displayed on LCD)
4. Change voltage to 3.50V accurately for the DC power supply.
* Check voltage at P.C. board test points because some voltage drops occur due to the usage of long or thin cable.
5. Press [TALK] key to write voltage value in EEPROM.
6. Turn the power off. Then this value is available.
Note:
For connection of DC power source and voltmeter, see
Handset Reference Drawing
(P.56).
