Operation
USING THE HTR 4 REMOTE CONTROL
BUTTON ILLUMINATION TIMEOUT
The HTR 4’s key-illumination can be set to remain lit for 0-9 seconds. The default value is 2 seconds. To set the illumination timeout, simultaneously press-and-hold for 3 seconds both the HTR 4’s [DISP] and the [0-9] key, with the digit corresponding to the desired timeout duration; the Learn LED will flash twice to confirm the new setting. When set to zero, the illumination will not turn on at all.
Note
Key illumination is the biggest drain on the HTR 4’s batteries. A short key-illumination timeout will extend battery life appreciably; turning it off altogether (set it to 0 seconds) will lengthen it still further.
FACTORY RESET
The HTR 4 can be reset to its factory state, deleting all learned commands, copied and punched- through keys, macros, and other setup information, reverting all keys to their pre-programmed library commands.
To perform a factory reset simultaneously press-and-hold for 10 seconds the HTR 4’s [ON] and [RTN] keys; the Learn LED will start to flash green. Release [ON] and [RTN] before the second flash is complete; the Learn LED will turn red, indicating the remote has been reset.
Note
You must release [ON] and [RTN] before the second flash goes out, otherwise the unit will not reset; should this occur, repeat the full procedure.
DELETE MODE
The HTR 4 can store learned, copied, and “default library” commands on any single key (The default library commands are the pre-programmed NAD codes, such as the native L 54 commands on the [AMP] “page.”).
You can delete commands by layers back “down” to the default library command on any key, removing learned commands, punched-through functions, and copied keys.
Note
The default library commands cannot be deleted, so you need not worry that using Delete Mode might cause irreparable changes.
To enter Delete Mode, simultaneously press-and-hold for 3 seconds both the desired key’s Device Selector key and the [RTN] key, until the Learn LED turns green. Press the function key whose command you wish to delete; the Learn LED flashes; the number of times indicates which type of function has become active - see the table below. Press the active Device Selector key again to exit Delete Mode.
Note
You may delete multiple function-key commands on the same Device Selector “page,” but to delete from more than one Device Selector page you must exit Delete Mode and then re-enter it on the required page.
