Items
(A) Charging Check
Note:
After the measuring, suck up the solder of TP.
The connection of adjustment equipment is as shown in Adjustment Standard (Charger Unit) (P.61).
Check
Point
- Follow steps 1 to 6 of (I).
7.Confirm that Power RAMP is matching.
- 1. Link with Handset.
2. Input -45 dBm/1kHz to MIC of Handset.
Measure the Level at Line I/F and distortion level.
3. Confirm that the level is -8.5 dBm ± 2 dBm and that the distortion level is < 5%
at TEL Line (600 Ω Load).
4. Input -20 dBm/1 kHz 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 -21 dBm ± 2 dBm and that the distortion level is < 5%
at Receiver (Volume Middle, 150 Ω Load).
1. Connect Charge Contact 12 Ω/2 W resistor between charge+ and charge-.
-
2. Measure and confirm voltage across the resistor is 3.10 V ± 0.2 V.
Check
Point
1. Connect Charge Contact 12 Ω/2 W resistor between charge+ and charge-.
