Transmitted Power 

Confirmation

-

Remove the Antenna before starting step from 1 to 4.

1. Configure the DECT tester (CMD60) as follows;

<Setting>

• Test mode: PP
• RFPI: 0102030405
• Traffic Carrier: 5
• Traffic Slot: 4
• Mode: Loopback
• RF LEVEL = -70 dBm

2. Execute the command “regcmd60 01 02 03 04 05”.
3. Initiate connection from DECT tester.
4. Confirm that the NTP value at ANT is 19 dBm ~ 24 dBm.

Modulation Check and 

Adjustment

-

Follow steps 1 to 3 of (G).

4.Confirm that the B-Field Modulation is -350 ~ -400/+320 ~ +370 kHz/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.)
