(F)* Battery Monitor
Confirmation &
Adjustment (Important)
- 1. Apply 2.3V ± 0.005V between TP3(+) and TP4(-) with DC power.
2. Execute the command “deactmac” to stabilize the value.
3. Then,execute the command “readbatt”.The returned value is XX.
4. Confirm that XX is between 98 and A8.
98 < XX < A8(Hex)
(If XX is out of range,change BBIC)

(H)* BBIC Clock Adjustment
(Important)
TP19 1. Apply 2.6V between TP 3(+) and TP 4(-) with DC power.
2. Execute the command “deactmac”.
3. Execute the command “conttx”.
4. Input Command “rdeeprom 00 01 01",then you can confirm the current value.
5. Adjust the frequency of TP19 executing the command “setfreq 00 xx (where xx
is the value)”.
so that the reading of the frequency counter is 10.368000MHz ± 10Hz.

(I)* Transmitted Power
Confirmation
TP15 Remove the Antenna before starting steps from 1 to 5. Replace C58 with
RESISTOR (0
Ω
). Be sure to mount C58 back to the same place after checking.
1. Configure the DECT tester(CMD60) as follows;
<Setting>
· Test mode: PP
·
RFPI: 0102030405
· Traffic Channel: 5
· Traffic Slot: 4
· Mode: Loopback
2. Execute the command “testmode”.
3. Execute the command “regcmd60”
4. Initiate connection from DECT tester.
5. Confirm that the NTP value at A201 (TP15) is 20dBm ~ 25dBm

(J) Modulation Check and
Adjustment
TP15 Follow steps 1 to 4 of (I) above.
5. Confirm that the B-Field Modulation is 340kHz/div ~ 402kHz/div using data
type Fig31.
6. Adjust the B-Field Modulation if required. (Execute the command “Readmod”
and “Writemod xx”, where xx is the value.)
