Clock accuracy
1. Antenna connect to antenna receptacle(Main side only)
2. Input the 98.1MHz/25dBu(1kHz,22.5kHz MOD) signal.
3. Connect a digital tester to TP1(DIV-TP) and adjust VR101 so that the reading
of digital tester is 0.6V +0.2/-0.2V.

Item Procedure
Measuring
instrument
1. Input a 98.1MHz/55dB(1kHz,30% MOD)signal.(0dB=1.4V)
2. Adjust the output to -22dB +3/-3dB(PP-2449V-B),-18dB +3/-3dB(PP-2449V-C)
by VR102 when the SSG output is set -20dBu.
1. Turn off and on the ACC switch,while holding CD EJECT button and POWER
button.Repeat it twice slowly.
2. Set a universal timer to TP201,adjust TC201 so that a reading of the meter is
0 sec +0.1/-0.1 sec/day.
