Backup Battery; Fuse; Power Management Modes - Honeywell Thor VM3 Manual

When the Thor VM3 is operated in an environment where the UPS battery is not able to charge due to temperature
extremes, the Thor VM3 should be removed to a location within the safe charging temperature range during off hours.
A discharged UPS battery cannot protect against data loss in the event vehicle power is interrupted.
Charging Timeout
• A fully discharged UPS battery normally recharges in less than 4 hours when the Thor VM3 is in a powered dock and
within the safe charging temperature range.
• If the UPS battery is not charged before an 8 hour timeout period expires, the
flashes super fast red.
• If the charge timeout occurs, remove the Thor VM3 from the dock and
the Thor VM3 in the dock and power on.
Charging and Power Management
• Charging does not occur when the Thor VM3 is in ignition mode and the ignition is inactive.
• Charging does not occur when either Ignition Mode power scheme/plan is selected and the ignition is inactive.
• Charging of the UPS battery continues when the Thor VM3 is in power management (user idle, system idle or
suspend modes).
• Charging of the UPS battery continues when the Thor VM3 is in power management (display off, sleep or hibernate
modes).

Backup Battery

The Thor VM3 has a permanent Lithium battery installed to maintain time, date and CMOS setup information for a minimum
of 90 days. The lithium battery is not user serviceable and should last four years with normal use before it requires replace-
ment.
Note: The backup battery should only be changed by authorized service personnel.

Power Management Modes

The Thor VM3 has four power modes: Full On, Standby/Sleep, Hibernate and Off.
Full On Mode
When the Thor VM3 is attached to either vehicle power or an external power supply or is operating from the UPS bat-
tery and the power button is pressed, the Thor VM3 is in the On mode. In this mode, the keypad, touch screen and any
attached peripherals such as a scanner function normally. The display remains on until the display, standby or hiber-
nate timer (if enabled) expires.
When in Full On mode, the status LED is solid green.
If the Thor VM3 is Full On, a press of the power button can be configured to put the unit in Standby. See the
What the Power Button Does
The Thor VM3 uses an 8A time delay (slow blow) fuse that is externally
accessible and user replaceable. The fuse is located on the back of the
dock. The fuse is accessed by unscrewing the cap as indicated.
Should it need replacement, replace with same size, rating and type of
fuse:
• Littelfuse 0215008.MXP
• Cooper Bussmann BK1/S506-8-R
• Bel Fuse 5HT 8-R
or equivalent.
Fuse has voltage on it even when power is off. Always disconnect input
power before changing the fuse.
