7.Execute the command "readrssi".
8. Confirm that the returned value is 22 ± A (hex).
- Follow steps 1 to 6 of (I).
7.Confirm that Power RAMP is matching.
- 1. Link with Handset.
2. Input -45dBm/1kHz to MIC of Handset.
Measure the Level at Line I/F and distortion level.
3. Confirm that the level is -10.5dBm ± 2dBm and that the distortion level is <
5% at TEL Line (600Ω Load).
4. Input -20dBm/1kHz to Line I/F.
Measure the level at Receiver of Handset and distortion level
(*Receive volume set to second position from minimum).
5. Confirm that the level is -20.5dBm ± 2dBm and that the distortion level is <
5% at Receiver (Volume Middle, 150Ω Load).
- 1. Connect Charge Contact 12Ω/2W resistor between charge+ and charge-.
2. Measure and confirm voltage across the resistor is 3.10V ± 0.2V.
