Point
- Remove the Antenna Jumper starting from 1 to 4
1. Configure the Spectrum Analyzer as follows;
• Center Frequency: 1924.992MHz
• Frequency Span: 10MHz
• RBW: 3MHz
• VBW: 3MHz
• Trace Mode: Max Hold
2. Execute the command "btx 00 02 0"
3. Execute the command "ANT 1"
4. Confirm that max power 15 ~ 20.5 dBm
- Remove the Antenna Jumper starting from 1 to 5
1. Configure the Signal Generator as follows;
• Frequency 1924.992MHz
• RF level = - 70 dBm
• Mode CW(modulaiton off)
2. Execute the command "CRX 00 00"
3. Execute the command "ANT 1"

% 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 -15 dBm ± 3 dBm and that the distortion level is < 5 %
at Receiver (Volume 2, 150 Ω Load).
- 1. TAM Confirmation (Execute the command "sendchar VPI")
2. Confirm the returned Value (Value is "DB07AA 01").
