Adjustment Point
- 1. Connect CN1 (Telephone Socket) to DTMF tester.
2. Execute the command "hookoff" and "dtmf_Hi".
3. Confirm that the high frequency (1477.06Hz) group is -3dBm ± 2dB.
4. Execute the command "dtmf_lo".
5. Confirm that the low frequency (852.05Hz) group is -6dBm ± 2dB.
- 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.
ANT Follow steps 1 to 6 of (I) above.
7.Confirm that the B-Field Modulation is 360kHz/div ~ 380kHz/div using data
type Fig31.
8.Adjust the B-Field Modulation if required. (Execute the command
"readmod" and "wrtmod xx", where xx is the value.)
- Follow steps 1 to 6 of (I) above.
7.Confirm that the frequency offset is < ± 50kHz.
- Follow steps 1 to 6 of (I) above.
7.Confirm that the frequency drift is < ± 30kHz/ms.
