6-1 Connecting External Speakers
The external speaker jacks on your Firestorm accept standard 3.5mm
plugs. When choosing an external speaker, it is recommended to use
one with an impedance rating of 8-ohms.
NOTE: Be sure the Firestorm is turned OFF before connecting an
external speaker.
To connect an external speaker, plug the connector of the external
speaker into one of the external speaker jacks. You will notice that each
external speaker jack corresponds with one of the internal speakers. For
example, internal front speaker and front external speaker are linked
together. If you wish to have ONLY the external speaker(s) produce
sound, you must disable the internal speakers as the internal speakers
are not disabled automatically.
6-2 Disabling Internal Speakers
Move the speaker slide switch to the “OFF” position for the desired
speaker you wish to disable (front or back). The following image shows
that each internal speaker has an independent on/off switch.
To re-enable the speaker later, simply place the slide switch back to the
“ON” position. By disabling the internal speaker(s) when using an
external speaker(s), battery life will be extended longer than having all
the speakers operating at once.
