was turned on is displayed in 1-hour increments.
The period of time during which the drum has been rotating is displayed 
in 1-hour increments.
The tape travel duration in the fast forward, rewind, play, search (JOG, 
VAR, SHTL), recording or editing mode (but not in the STILL mode with 
JOG, VAR and SHTL) is displayed in 1-hour increments.
The number of times the tape has been threaded or unthreaded is 
didplayed in 1-time increments. 
						

							Video head cleaning
This laptop has an auto head cleaning function which automatically reduces the amount of dirt on the heads. However, for even
higher reliability, it is recommended that the video heads be cleaned every day.
Use the cleaning fluid designated by Panasonic.
Condensation
The principle behind the formation of condensation is the same as that which causes droplets of water (condensation) to form
on the window panes of a heated room when it is cold outside. Condensation forms on the laptop or tape when it is moved to a
location with a significantly different temperature and humidity. More specifically, it forms when the laptop of tape is:
¥ Taken to a very steamy and humid location or into a room where the heating was just turned on.
¥ Taken suddenly from an air-conditioned room to a very hot and humid location.
In such cases, do not turn the power on immediately but leave the unit standing for about 10 minutes. When condensation has
formed in the unit, ÒdÓ appears on the counter section. Keep the power on and wait until ÒdÓ is cleared.
Maintenance
Before proceeding with maintenance, set the power switch to OFF and be sure to take hold of the power plug to disconnect the
power cable from the power outlet.
Use a soft cloth to clean the cabinet. To remove stubborn dirt, dilute some neutral detergent with water, dip a cloth into the solu-
tion, wring it out, and wipe away the dirt. Then wipe off any remaining moisture using a dry cloth.
Cautions
Do not place the video cassette on top of bed covers or carpet when in use.
