DSP-2
The DSP-2 is a highly-effective filtering technology which can dramatically improve re-
ception and transmission.
1. Turn the transceiver’s power off by pressing and holding in the POWER switch for one
second, then disconnect the DC cable from the INPUT jack on the rear panel of the
transceiver.
2. Referring to Figure 1, remove the seven screws affixing the top cover of the transceiver
then disconnect the speaker’s connector from the MAIN Unit.
3. Refer to Figure 2, locate the empty 16-pin connector, and connect the DSP-2 here.
4. Move the small switch which is located beside the 16-pin connector to the “D” position.
5. Replace the top cover and its seven screws (remember to replace the internal speaker’s
plug).
6. DSP-2 installation is now complete. Connect the DC cable to the INPUT jack.
