Point
1. Apply 2.3V ± 0.005V between BATTERY (+) and BATTERY (-) with DC power.
2. Execute the command "deactmac" to stabilize the value.
3. Then, execute the command "readbatt". The returned value is XX.
4. Confirm that XX is between 98 and A7.
98 < XX < A7 (Hex)
(If XX is out of range, change BBIC)
1. Apply 2.40V between BATTERY (+) and BATTERY (-).
2. Confirm that there is no Speaker sound (Battery low alarm).
3. Apply 2.2V between BATTERY(+) and BATTERY(-).
4. Confirm that there is Speaker sound (Battery low alarm).
1. Apply 2.6V between BATTERY (+) and BATTERY (-) with DC power.
2. Execute the command "EnableClockOutput".
3. Input Command "sfr", then you can confirm the current value.
4. Check X'tal Frequency. (10.368 MHz ± 100 Hz).
5. If the frequency is not 10.368 MHz ± 100 Hz, adjust the frequency of CLK
executing the command "setfreq xx xx (where xx is the value)" so that the
reading of the frequency counter is 10.368000 MHz ± 5 Hz.
Note:
* How to de-registration (link to base unit)
1) Push handset: menu → # → 1 → 3 → 1
2) Push handset: 0 → 0 → 0 → 0
3) Select handset you want to de-regist.
After push OK.
Register to it on Base Unit after measurement.
Remove the Antenna before starting steps from 1 to 5.
1. Configure the DECT tester (CMD60) as follows;
<Setting>
• Test mode: PP
• RFPI: 0102030405
• Traffic Channel: 5
• Traffic Slot: 4
• Mode: Loopback
2. Execute the command "testmode".
3. Initiate connection from DECT tester.
4. Confirm that the NTP value at ANT is -19dBm ~ 25dBm.
Follow steps 1 to 4 of (I).
4. Confirm that the B-Field Modulation is 340kHz/div ~ 402kHz/div using data
type Fig31.
Follow steps 1 to 4 of (I).
4. Confirm that the frequency offset is -50kHz ~ +50kHz.
Follow steps 1 to 4 of (I).
4. Set DECT tester power to -85dBm.
5. Confirm that the BER is < 1000ppm.
Follow steps 1 to 4 of (I).
4. Confirm that the Timing accuracy is < ± 2.0ppm.
Follow steps 1 to 4 of (I).
4. Set DECT tester power to -70dBm.
5. Execute the command "readrssi".
6. Confirm: 9 < returned value < 13 (hex) (0E ± 5 (hex))
