Transmitted Power
Confirmation
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. Execute the command "regcmd60"
4. Initiate connection from DECT tester.
5. Confirm that the NTP value at ANT is 20dBm ~ 25dBm

Modulation Check and
Adjustment
Follow steps 1 to 4 of
(I)
above.
5. Confirm that the B-Field Modulation is 340kHz/div ~ 402kHz/div using data type Fig31.
6. Adjust the B-Field Modulation if required. (Execute the command "Readmod" and
