Does the battery power the locking function or just the lighting function?

You need power to engage the locking/unlocking deadbolt knob. Without the battery, you have to use the key.

You have a turn key to lock and un-lock the door. the battery is for the light and the keypad itself.

locking and unlocking are done by manually turning the lever. The battery is needed to engage or disengage the mechanism that allows the lever to lock or unlock.

As has been stated, the battery engages the knob, allowing you to manually retract or extend the bolt. This probably greatly extends the life of the battery, by letting the user do the work of moving the bolt. When the battery gets low, you'll be warned by a a delay before unlock, a High/Low beep then 1 Red then Green light flash. Once it's dead the keypad will not function. The key will always work.

The battery power DOES NOT retract or extend the deadbolt. That is done manually. The battery powers the light and the keypad + mechanism that allows you to engage or disengage the deadbolt.

As far as I know battery power is needed to unlock. So may want to change he battery periodically, say once a year, not when it fails ( or you may still carry a real key). I haven't replaced the battery yet. We love this lock. Also, you should be ale to locate the manual online.

Both, when you press the keys, the they light up. I have had mine for 3 years now and just bought one for my daughters new house. I love this, you'll never lock yourself out. There is also a key if you need it, but the unit lets you know when to change the battery, it does last a long time though. I hope this helps!

Battery powered. Not sure about the back lit part since I bought it as a gift

My experience has been that the light is on when it is working. I don't know if the light goes out when the battery is fully charged.

Yes it does. All is set to go. Has to be hard wired by electrician and the battery powers the light when the power goes off. Very nice light for the money.

Upon going into battery activation, the unit uses the low setting for the light power. The available settings for normal operation are low and high; both are actually pretty bright. Battery light setting is fixed; would be nice if it too was adjustable. The level of lighting is very relative and very hard to measure; especially the concept of radius (ending at which level of light, etc). However it is a substantial level even on low. Generally brighter than a lot of the night lights that we have bought prior.

It depends is the outlet on a timer or are you going to manually cut the power to the lock.

The lock has two parts, "A" fits on the outside of the door "B" fits on the inside. They fit over the hole that is cutout for the knob. the "A" part with the lever handle is on the outside, it has a wire that goes through the hole in the door and plugs in to the "B" part on the backside were the battery is. Battery pack is on the inside of the door ("B").

i'm not exactly sure... but I think the lock switch disables all functions to avoid pocket unintended turn ons.

Both, that is, it functions as a desk lamp whether plugged in or not. In the presumably normal (plugged in and power on) mode, one merely depresses the button located on the base. Should power fail and/or the lamp be/become unplugged, one merely needs push the button located just behind the lens assembly, et voila, "let there be light." Finally, the "head" detaches to provide a highly portable, battery operated flashlight of considerable brightness.

This is from their installation manual: Programmable lock-hold time from 1-9 seconds (default at 3 seconds) Note: Longer lock hold time will reduce battery life when using alkaline batteries

No, just the lock. You must supply the power and something to control the power like a switch or relay.

They provide a couple of keys to manually open the lock. There is also a warning beep to remind you to change the batteries when power gets low.

The clock uses both battery and ac power. The battery operates the clock itself, while the ac powers the camera etc.

It works either way. Noisy lock mechanism. Batteries do not last as advertised.

where it shows the "1" when lite up it shows your number locks are on and the "A" lights up shows your caps are on. if you push down the caps button the light will go on/off and same with the num lock. hope this helps

Correct. The backlight is on as long as the device is getting volts. The internal battery is just an LR44 button cell that keeps the time and temperature functions running.
