turn these on and off with the TX-24 remote control transmitter. However, there
are some strict electrical limits involved with this jack. If these limits are
exceeded, damage to your SPITFIRE will result. This damage is not covered by
warranty.
The electrically inclined will want to know that the jack is connected to the drain
of an internal Field Effect Transistor with a maximum current rating of 2
Amperes. The “tip” polarity of the 3.5mm jack is positive, while the sleeve is
negative. If the external device is connected with the polarity reversed, an
internal protection diode within the FET will conduct, causing the device to stay
on constantly. The maximum voltage applied to this jack must never exceed 15
volts.
Typical uses for this jack would be to control the FOXPRO Jack-in-the-Box
Decoy or to start and stop a video recorder. Instructions on connecting various
devices to the “AUX” jack are beyond the scope of this manual. You are urged
to seek help from a knowledgeable professional before connecting any
unapproved device to this jack. Remember that damage to your Spitfire
caused by improper use of the “AUX” jack is not covered by the warranty, nor
will FOXPRO be liable for damage to any devices connected to this jack.
3.0 USING AN EXTERNAL SPEAKER
The SPITFIRE is equipped with an External Speaker Jack, which allows you to
connect an additional speaker.
3.1 CONNECTING AN EXTERNAL SPEAKER
The external speaker jack on your Spitfire accepts 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 Spitfire is turned OFF before connecting an external
speaker.
To connect an external speaker, plug the connector of the external speaker into
the external speaker jack. If you wish to have ONLY the external speaker
produce sound, you must disable the internal speaker with the “SPKR” slide
switch on the Spitfire, as the internal speakers are not disabled automatically.
3.2 DISABLING INTERNAL SPEAKER
Move the speaker slide switch to the left or “off” position to disable the internal
speaker. To re-enable the speaker later, simply place the slide switch back to
the right or “on” position. By disabling the internal speaker when using an
external speaker, battery life will be extended longer than having both of the
speakers operating at once.
