TSG 601 User Manual
ment by sliding the compartment door in the direction of the in-
scribed arrow until the door tabs line up with the slots in the case,
then remove the door. When selecting a power source for your
TSG 601, please remember:
H Attempting to use an improper AC adapter can cause permanent
damage to the instrument. USE AN APPROPRIATE DC POWER
SOURCE ONLY: Voltage must be between 9 and 15 VDC; the
center contact of the connector must be NEGATIVE polarity; and
open-circuit voltage must not exceed 18 VDC. For best results,
use the adapter supplied with the instrument.
H There is no need to remove the optional NiCad battery pack for
recharging. The TSG 601 will “trickle charge” the battery pack
whenever the standard AC adapter is used. It can take up to 16
hours to fully charge the battery pack. Note that charging will
occur only if the adapter supplies at least 12V; make sure that the
adapter you use is appropriate for the local AC supply.
H AA batteries are not included with the instrument; buy them
locally. Rechargeable AA batteries may be used, but they are
NOT recharged automatically. To recharge AA batteries, remove
them from the instrument and use an appropriate battery charger.
For safety, read and follow the battery charger instructions. Do
NOT attempt to recharge standard alkaline batteries.
H After a minute with no key press, the display back light will be
dimmed to conserve battery charge.
H To guard against battery discharge if you forget to turn the
TSG 601 off, enable Auto Power Down through the Diagnostic
menu (see page 56).
H The TSG 601 can sense low battery voltage. It will warn you
when the charge is sufficient for approximately ten more minutes
of operation. The instrument will shut itself down when the bat-
tery voltage becomes too low for reliable operation. See the Bat-
tery hints in Appendix C, beginning on page 55 of this manual.
The ON key toggles instrument power On and Off.
