Confirm that the high frequency (1477.06Hz) group is -6dBm ± 2dBm.4. Execute the command "dtmf_lo".5. Confirm that the low frequency (852.05Hz) group is -8dBm ± 2dBm.6. Execute the command "dialtone 0".IC2, R39, C41,R49, C46, C47,R43, R44, R45,R46, R47, R48,C40, C108,C109,C36, R42,Q8, D4, R34(J)* Transmitted PowerConfirmation- Remove the Antenna before starting step from 1 to 7.1. Configure the DECT tester (CMD60) as follows;•••• 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.IC2, L1, C63,C84, C71, C73,C104, C62,C59,C64, C100,C58,C57, C105,C55, C82, C72,R59, R60, R61,R112, R113,R91, R92,L3, DA1RFM1, C311,C312, C320,C322, C323(K) Modulatoin Checkand AdjustmentANT Follow steps 1 to 6 of (J) above.7.Confirm that the B-Field Modulation is 360kHz/div ~ 380kHz/div using datatype Fig31.8.Adjust the B-Field Modulation if required.
