Jolida JD 700

Help! Jolida JD700.
I have lost my remote and cannot turn the volume up.

Jolida will not help.

Anyone else ever have this issue?  Any Universal remotes out there work?
The database for Harmony universal remotes lists the Jolida JD700 as being compatible. Get one of their inexpensive ones, set up an account on the Harmony site and download the commands to the remote from your computer.

The Jolida doesn't have a volume knob??!
