Lost manual for model # 880 need to

Number 1, there are 2 versions of the Logitech 880 Harmony:

You have either the (standard) 880 Harmony, or
the (PRO) 880 Harmony.

Number 2, BOTH versions require a BASE UNIT to RECHARGE the batteries.

I have located the user manual for the standard model here:

Alternately, the user manual for the "PRO" model is located here:

Hope this helps!

First, check your battery indicator (make sure it's fully charged).  Second, dock your remote with the USB cable and reprogram the remote.  It's possible you disconnected before the programming was properly transmitted to your remote.  Finally, if things don't work, use the HELP button on the remote.  It should talk you through a procedure to fix your problem.

Was it working before?  Is it possible you selected the wrong brand of TV when programming the remote?  Do you use a cable box or satellite dish with your TV (in other words, do you change channels by changing the channel on the TV, or on the digital box connected to your TV)?

you may need to reprogram your remote, or, if you have your profile setup on the harmony website, reload from there
