HiRO presenters are working at the frequency of 2.4GHz. However, there are other devices that work within this frequency as well, such as cellular phone, cordless phone, or even microwave oven. Therefore, it is possible that the presenter's link with USB transmitter may be interfered by those neighbors.
The symptom of broken link between presenter and USB transmitter is that all the buttons & directional pad are not functional. However, the laser pointer should still work because this feature does not require any communication with USB transmitter. Therefore, please follow the steps below:
(1) Please refer to the following URL to see if the laser pointer is working or not.
How to activate/deactivate the laser pointer
If the laser pointer is working, please go to the 2nd step. Otherwise, please contact us at service@hiroinc.com
(2)Please refer to the following URL to re-establish the link:
How to re-establsih the link between presenter & USB transmitter
You can purchase 2 sets of our presenters
1. Plug in both receivers on both computers and use either 1
of the presenters to control 2 or more computers. (Only w/ factory default
channels)
2. You and your colleague could use both presenters to change
pictures at the same time on both computers.
If you don’t relink them, both will stay on a factory default channels and
you’ll be able to control 2 computers using either or both of the presenters.
However, if you found that the presenter is not connecting to the receiver (for
some reason, varies) or you don’t want each other to be interfered with, you’ll
need to relink it. (School teachers, for example. Each one using their own
presenter at the same time and of course, none of them want to control the
other’s computer.)
Once you relink the presenter, you’ll lose the sync
capability and each presenter will only link to the receiver you relink with.
If you want to be able to control 2 computers or more using one presenter,
you’ll need to purchase another new set of presenter (set on a default channel)
to be able to control 2 computers at the same time.
That is to say, once the connection is reestablished (reset/relink), the
channel settings will change and the newly paired presenter and receiver will
be set to one of the 65k channels and won’t be able to reset back to factory
settings.
