Point
- 1. Apply 2.25 V between BATT+ and BATT-.
2. Execute the command
sendchar PAD
sendchar LED 0
sendchar CRX 0 1
sendchar AD1
It assumes that the return value is XX.
a) XX: 70: No need to adjust
b) XX: 66 ~ 6F: Need to adjust
XX: 71 ~ 7A: Need to adjust
Write AD value of 2.25 V to EEPROM.
ex) read data: XX = 6A, write data: YY = 6A
read data: XX = 73, write data: YY = 73
EEPROM = 0009(Low Voltage) write "YY"
Execute the command "wreeprom 00 09 01 YY".
EEPROM = 000A(No Voltage) write "YY -C"
Execute the command "wreeprom 00 0A 01 ZZ".
Note:
ZZ = YY - C
c) XX: 00 ~ 65: Reject
XX: 7B ~ FF: Reject
- 1. Apply 2.40 V between BATT+ and BATT-.
2. Confirm that there is no flashing of Battery Icon.
3. Apply 2.25 V ± 0.08 V between BATT+ and BATT-.
4. Confirm that there is flashing of Battery Icon.
CKM 1. Apply 2.6 V between BATT+ and BATT- with DC power.
2. Input Command "sendchar sfr", then you can confirm the current value.
3. Check X'tal Frequency. (10.368 MHz ± 100 Hz).
4. If the frequency is not 10.368 MHz ± 100 Hz, adjust the frequency of CKM
executing the command "sendchar sfr xx xx (where xx is the value)" so that the
reading of the frequency counter is 10.368000 MHz ± 5 Hz.
Note:
Clear the registered information for Base Unit before measurement, because the
Frequency will not possibly get stable due to the registered information.
Pressing the button of "3" "5" "7" "#"clears the registration.
Register to it on Base Unit after measurement.
- Short Antenna pattern to GND.
1. Configure the DECT tester (CMD60) as follows;
<Setting>
• Test mode: PP
• RFPI: 0102030405
• Traffic Carrier: 5
• Traffic Slot: 4
• Mode: Loopback
• RF LEVEL = -70 dBm
• PACKET: PP32Z
2. Execute the command "sendchar TST 01 02 03 04 05".
3. Initiate connection from DECT tester.
4. Confirm that the NTP value at ANT is 19 dBm ~ 25 dBm.
- Follow steps 1 to 3 of (I).
4.Execute the command "read RSSI"
5.Confirmed that the returned value is 21 A (hex)
- 1. Link to BASE which is connected to Line Simulator.
2. Set line voltage to 48 V and line current to 50 mA.
3. Input -45 dBm (600 Ω)/1 kHz to MIC of Handset. Measure the Level at Line I/F
and distortion level.
4. Confirm that the level is -3 dBm ± 5 dB and that the distortion level is < 5 % at
TEL Line (600 Ω Load).
5. Input -20 dBm (600 Ω)/1 kHz to Line I/F. Measure the Level at Receiver of
Handset and distortion level (Receive volume set to second position from
minimum).
6. Confirm that the level is -27 dBm ± 4 dB and that the distortion level is < 5 % at
Receiver (34 Ω Load).
- 1. Link to Base which is connected to Line Simulator.
2. Set line voltage to 48 V and line current to 50 mA.
3. Set the handset off-hook using SP-Phone key.
4. Input -30 dBm (600 Ω)/1 KHz to Line I/F and measure Receiving level at SP+
and SP-.
5. Confirm that the level is -7 dBm ± 3 dB and that the distortion level is < 5 %.
(vol = Max at SP (8 Ω Load))
