Please note: please do not confuse this remote control (frequency 26.995 MHz and 10 switches) with the similar-looking model EINHELL F2000-1 (same frequency, but with 9 switches) or with the model EINHELL F1024-1 (frequency 27.015 MHz). Please verify the frequency that is written on the remote control or on the quartz (inside the casing), as well as the number of switches inside your remote control. Remote controls with different frequencies are not compatible.
