Can I operate other DEX devices while the CROS is on?
Simultanous streaming from both the CROS and another DEX device is not possible, however, if the signal from another DEX is stronger than CROS, it will override the CROS signal. It all depends on the signal strength of the DEX device relative to the CROS. For example, if PHONE-DEX is held up to the aided ear, the PHONE-DEX will stream to the hearing aid, replacing the CROS signal. If the DEX connection is unstable, turn off the CROS.
