(I)* Transmitted Power
Confirmation
- Remove the Antenna before starting step from 1 to 7.
1.
Configure the DECT tester (CMD60) as follows;
<Setting>
· Test mode: FP
·
Traffic Carrier: 5
· Traffic Slot: 4
·
Mode: Loopback
· PMID: 0000
· RF LEVEL = -70dBm.
2. Execute the command "testmode".
3. Execute the command “sendchar dmv 2 2“.
4. Check that “Signalling Status” has been set to “Locked“, then press
“ACCEPT RFPI“.
5. Initiate connection from Dect tester (“set up connect“)
6. Execute the command “ant0“.
7. Confirm that the NTP value at ANT is 20dBm ~ 25dBm.
