Point
- 1. Apply 2.25 V between BATT+ and BATT-.
2. Execute the command
sendchar PAD
sendchar LED 0
sendchar AD1
It assumes that the return value is XX.
a) 6D xx
b) xx: 6B ~ 6C: Need to adjust
xx: 73 ~ 75: Need to adjust
Write AD value of 2.25 V to EEPROM.
ex) read data: xx=6B, write data :yy=6B
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-C''
Execute the command "×wreeprom 00 05 01 ZZ".
Note:
ZZ = YY - C
No Voltage writing data limit is '00'.
c) xx:00 ~ 6A: reject
xx:76 ~ 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.
X_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 ~ 24 dBm.
- Follow steps 1 to 3 of (I).
4.Confirm that the B-Field Modulation is -300 ~ -402/ +300 ~ +402 kHz/div &
Modulated width
Procedure
72: No need to adjust
670kHz/div using data type Fig 31.
