AESS
(Acoustic Enhanced Speaker System)
The combination of the internal speaker on top of the transceiver with the external speaker
“SP-40”, reproduces high-quality received audio with a wide frequency range and a three-dimensional
acoustic e󰀨ect. Set the optimum sound quality by adjusting the output balance and frequency characteris-
tics of the two speakers according to your preference.
• The AESS is designed to function optimally with the included speaker “SP-40”. It will not perform properly
with other speakers.
• When moving or transporting the FT-710, remove the SP-40 to prevent it from falling o󰀨.
SP-40 connections
The SP-40 can be mounted on either the left or right side of the transceiver.
