GunVault HV 5900 - Manual (Page 12)

- 12 -
Any interruption of power will cause the computer memory to reset to the factory code: one, two, three,
four. If this occurs, anyone who enters the one-two-three-four code will gain access to the safe and its
contents.
Warning: Never attempt to plug in a battery charger of any kind. Fire or explosion of batteries could
result. Never use rechargeable batteries of any kind in a GunVault safe. Their power characteristics
are not compatible with the safe.
The AC/DC power supply specified is NOT a battery charger; it is an external power supply to be used
only when batteries are installed.
11. Maintenance
Low Battery Warning Indicator
The low battery indication on standard models is seven red flashes and seven soft beeps when the valid
access code is entered. This indication means that insufficient power is available from the battery tray-
the unit may continue to work normally, but the batteries must be changed immediately. Check battery
tray and battery tray installation, connections, orientation of batteries, and condition of batteries. You
cannot program your safe while the light is blinking
Battery Replacement
Warning: Replace the batteries once a year regardless of whether or not the low battery
indication is observed.
Always check carefully to be sure that all of your batteries are facing in the correct direction. One
battery facing the wrong way will lower the power output of your battery tray, potentially causing
unreliable operation.
IMPORTANT: We recommend that you use ONLY Duracell AA batteries. Eight (8) AA batteries
are required. NEVER attempt to use rechargeable batteries – they will not work!
Lubrication
It’s a good idea to lightly coat the door hinge spring and door latch-loop with quality oil at least once a
year. Never spray anything into the latch mechanism.
