Page "Bell TV" Paragraph 17

Many types of remotes have been released over the years.

Models 1000 and 2700 came out with very basic infrared ( IR ) remotes that could be used only to control the receivers themselves and would operate on all 16 remote addresses.

Replacement remotes then came with universal functions allowing users to control the power and volume of their televisions along with VCRs and sound system receivers ; these remotes can only operate on a single address at a time.

Models equipped with a UHF antenna can respond to UHF remotes ; these remotes use radio frequencies rather than IR signals to control the receivers.

UHF signals can reach up to 30 meters, depending on the restrictions of building materials.

All UHF-compatible receivers can simultaneously respond to IR signals except for model 4500.

For this model, modification directions exist on the Internet to add IR receiving capability, in order for the receiver to respond to programmable universal remotes.

Remote # 2 of the 3200, 5200, 9200, and the remote for model 6100 are based on " UHF Pro ".

" UHF Pro " remotes are strictly compatible with the receivers they are provided with and do not function on regular UHF-compatible receivers.

Additionally, " UHF Pro " remotes can only communicate with UHF frequencies and cannot control receivers via IR.

To prevent interference with other UHF remotes in proximity, clients should change their remote addresses.

All secondary remotes for dual tuners may also be converted to remote # 1 by flipping the plastic bottom of the remote.

This also switches its transmission mode from UHF Pro to regular UHF and IR, similar to how a 5900 remote operates.
