3-3. Releasing the HUMID TIMER when
Condensation Occurs
To protect the tape when dew condensation occurs,
HUMID ALARM is displayed, and the VTR stops for a
specified time set by the HUMID TIMER.
HUMID TIMER is a timer to stop operations for protecting
the tape when condensation occurs. It is a function
provided for the unit to clear condensation naturally.
When the condensation is cleared manually, the HUMID
TIMER will not be turned off even when there is no
condensation, and the unit will not operate.
To clear the condensation manually, and to operate the
VTR, turn OFF the HUMID TIMER as follows:
1. Set the unit in SYSTEM MENU (Refer to section 4-1-
2), and set the HUMID TIMER OFF mode (Menu No.
509).
* X X X indicates the remaining time.
2. Press the RESET button twice, and if X X X becomes
0, it means that the HUMID TIMER has been turned
off.
n
If HUMID TIMER is not released by performing items 1
and 2, condensation is not completely cleared, therefore,
clear condensation one more.
