Hi all Just bought my CB1100 RS yesterday and this morning I noticed the HISS light is flashing. The ignition is off, the key isn't in the bike, yet this light is flashing Is this normal or should I be concerned?
Update I have got off my rear and found out myself as I should have
It is normal and can be switched off using the buttons on the dash

Does HISS have higher battery requirements, especially during long periods of storage?

Does HISS have a radio chip, or is it hard-wired into the key and detected upon insertion? If the latter, then no additional power requirement is necessary.

The hiss key has a universal cartridge inside the black plastic cover ( google " id46 " ) which has a very small ferrite rod with a resonant winding and a chip with the code programmed into it.
Once the key is inserted and the ignition switched on the black ring around the key emits a 100khz signal which energizes the chip which responds with a set of "short circuit" pulses which changes the 100 khz transmitter, the code is verified by the receiver ring, communicated to b10 and b11 of the ecu and the ignition is then activated.
I have listened to it with a long wave receiver close by and could hear the short tone burst at switch-on.
On some bikes it is possible to copy up to 3 keys as i recall through a sequence, there is some info about it on the net.
And the hiss led uses a meager amount of energy which stops after 24 hours until the ignition is once again used and the correct key is recognised, the clock also uses power but again this is much smaller than the self-discharge current of the battery so " no worries " as they say over here, good question.

would that be really serious , that would certainly have been hotly debated for many years ?

As max (above) has texted, HISS keys are directly engaged. That implies energy is not used while parked and ignition off.
