Confirm that the high Group is -3 ± 2dBm.5. Confirm that the low Group is -6 ± 2dBm.IC7, R67, IC6,R116, C141,R29, C22, C23,R18~R24,C14~C17, Q5,D4(I)* Transmitted Power Con-firmation- Remove the Antenna before starting step from 1 to 7.1. Configure the DECT tester (CMD60) as follows;• Short A_1 and GND.• Test mode: FP• Traffic Carrier: 5• Traffic Slot: 4• Mode: Loopback• PMID: 00000• 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 “ACCEPTRFPI”.5. Initiate connection from Dect tester (“set up connect”)6. Execute the command “ANT1”.7. Confirm that the NTP value at ANT is 20dBm ~ 25dBm.IC7, IC10, L7,L3, L4, L6,C117, C118,C119, C120,C124, C125,R106, R109,DA1, C102,R102, R103,Q10, C110,C112, R111,C126, C127,R112(J) Modulation Check andAdjustment- Follow steps 1 to 6 of (I).7.Confirm that the B-Field Modulation is -350 ~ -400/+320 ~ +370kHz/div usingdata type Fig31.8.Adjust the B-Field Modulation if required.
