Transmitted Power
Confirmation
Remove the Antenna before starting steps from 1 to 4.
1. Configure the DECT tester (CMD60) as follows;
<Setting>
•
Test mode: FP
•
Traffic Channel: 5
•
Traffic Slot: 4
•
Mode: Loopback
•
PMID: 00000
2. Execute the command "testmode".
3. Initiate connection from DECT tester. (“set up connect”)
4. Confirm that the NTP value at ANT is 20dBm ~ 25dBm.

Modulation Check and
Adjustment
Follow steps 1 to 3 of
(H)
above.
4. Confirm that the B-Field Modulation is 340kHz/div ~ 402kHz/div using data
type Fig31.
5. Adjust the B-Field Modulation if required. (Execute the command "readmod"
and "wrtmod xx", where xx is the value.)
