1) Basic Operation Test
<Startup and initial condition>
Fit a battery or a dummy battery in the set. Hold down the "End/Power" key to start up in the general mode. Then enter
AT+XDIAG without pressing any key.
Back light OFF
After startup, "H/W CHECK ∗ GX-10i ∗" is displayed.
When adjusting by the AT command, be sure to perform the LDDEVPRM command before adjustment and the SVDEVPRM
command after adjustment.

Test Method
Before adjustment perform this
command to output the adjustment
value stored in FROM to SRAM.
Checking that LEDs light up.
LED1: Main-screen display
back light lights up.
LED2: Green LED lights up.
LED3: Red LED lights up.
LED4: Key back light lights up.
LED0: All LEDs light off.
Checking frequency of the real time
clock.
Normal: When OUT32K1 is transmitted,
TP205 frequency is 32.768 kHz ±1.11
kHz.
Reading the voltage of the battery
power line. BATVAL is transmitted,
"OK" and the voltage value are
returned.
Writing time to the clock.
When RTCWR yymmddhhmmss is
transmitted, yy (year), mm (month),
mm (hour), and ss (minute) are written.
Reading time of the clock. When
RTCRD is transmitted, time of day is
read out.
Refer to the "Adjustment procedures
after replacement of parts" on pages
2 – 36 and 2 – 37.
Reading temperature measured by
the temperature sensor.
When TMP is transmitted, TM and
temperature are returned. In case of
other than 0 – 50 ˚C, "NG" is returned.
