Hi 1299cc and

to the Club !
( Check your PM's re the Tank Bag Strap !)
As stated the Ignition Key has no buttons to press,
the Trophy is fitted with an Ignition Immobiliser, ( it is NOT an "Alarm" )
where the Key(s) contain a Transponder that is detected
by an antenna at the Ignition Switch.
If the Transponder is not present, the engine will not start.
You can get an additional Alarm Accessory ( Datatool S4 )
which comes with a Remote Key Fob to Arm and Disarm it.
The Power Socket next to your left Knee is very convenient for connecting a Battery Optimiser,
such as the Optimate, and an Adapter is available from your Triumph Dealer to connect an Optimate.
The Socket is a "Powerlet" / "DIN" / "Hella" type, and not the usual "Cigar Lighter" socket.
Also, check your Main Bettery ( Remove the cover under the right handlebar grip by undoing 1 screw,
then lifting the rear edge of the cover and pulling it up and back to release the front retaining pegs ).
You may find that there is already a "Fly-Lead" connnected to the Battery, with a an Optimte in-line connector,
which some Members prefer rather than using the Powerlet socket.
You don't need to worry about the "Sound System Battery draw down" issue that
karl mentions.
That problem only affected US & Canadian export models with the XM Satellite Radio system.
Cheers
