Point
- 1. Apply 3.5 V between CHG(+) and CHG(-) with DC power supply and set cur-
rent limit to 250 mA.
Confirm the indication of "charging" on LCD.
2. Confirm that the current limit LED of DC power supply is ON/OFF.
Confirm it after waiting over 1 minute at least.
3. Decrease current limit of DC power supply to 100 mA.
4. Confirm that the current limit LED of DC power supply is stable. (Current limiter
is ON.)
(If charge control cannot be confirmed by this procedure, please use battery to hand-
set power supply and try again.)
- 1. Stop supplying 3.5 V to CHG (+) and CHG (-).
2. Confirm the indication of "charging" has been cleared.
- 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) 6c XX
b) XX: 6A ~ 6B: Need to adjust
XX: 72 ~ 74: 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 = 0004(Low Voltage) write "YY"
Execute the command "wreeprom 00 04 01 YY".
EEPROM = 0005(No Voltage) write ''YY - 1D''
Execute the command "×wreeprom 00 05 01 ZZ".
EEPROM = 000A(Low Voltage BL) write "YY - 16"
Execute the command "wreeprom 00 0A 01 WW".
Note:
ZZ = YY - C
No Voltage writing data limit is '00'.
c) XX: 00 ~ 69: Reject
XX: 75 ~ 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.
CLK 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 CLK exe-
cuting 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" "7" "9" "#" clears the registration.
Register to it on Base Unit after measurement.
- Remove the Antenna before starting step from 1 to 4.
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.
