Adjustment
-
1. Apply 2.3V ± 0.005V between BATT(+) and BATT(-).
2. Execute the command "Backloff", then “readbatt“.
3. Confirm: 29 returned value 36 (Hex)
(If the returned value is within the range, no need to do step 4 and 5.)
4. If the reading is out of range in step 3 above, adjust the battery monitor excuting
command “wreeprom 00 01 01 XX”. (XX is the reading at step 3.)
Then excute command “wreeprom 00 36 01 YY”. (YY= XX - 0E)

Confirmation
-
1. Apply 2.40V between BATT(+) and BATT(-).
2. Confirm that there is no flashing of Battery Icon.
3. Apply 2.20V between BATT(+) and BATT(-).
4. Confirm that there is flashing of Battery Icon.
(I)* BBIC Clock
Adjusment
CLK
1. Execute the command "conttx".
2. Input Command “rdeeprom 00 57 01”, then you can confirm the current value.
3. Adjust the frequency of CLK executing the command "setfreq xx (where xx is the
value)" so that the reading of the frequency counter is 10.368000MHz ± 10Hz.

Confirmation
- Remove the Antenna before starting step from 1 to 4.
1. Configure the DECT tester (CMD60) as follows;
<Setting>
-Test mode: PP
-RFPI: 0102030408
-Traffic Carrier: 5
-Traffic Slot: 4
-Mode: Loopback
-RF LEVEL = -70dBm
2. Execute the command "regcmd60 01 02 03 04 08".
3. Initiate connection from DECT tester.
4. Confirm that the NTP value at A201 (TP15) is 20dBm ~ 25dBm.

Modulatoin
Check and
Adjusment
- Follow steps 1 to 3 of (J) above.
4.Confirm that the B-Field Modulation is 360kHz/div ~ 380kHz/
div using data type Fig 31.
5.Adjust the B-Field Modulation if required. (Execute the
command "Readmod" and "wrtmod xx", where xx is the
value.)
