between viewing DIRECTV channels, viewing video from your DVD player, or running your game system by changing the input source.
Dolby Digital Audio: Dolby® Digital audio is recorded on six separate channels, each of which can be heard on one of six separate speakers. To use Dolby® Digital audio, you must use an optical audio cable to connect your DIRECTV DVR to an A/V receiver capable of supporting Dolby® Digital audio. Not all A/V receivers with optical audio inputs are capable of receiving Dolby® Digital audio. You must also set your DVR to record using Dolby® Digital audio. For more information, see page 96.
Dolby Surround Sound: Dolby® Surround Sound audio is recorded on two channels, which can be heard on two or more (usually five) speakers. To use Dolby® Surround Sound audio, you must have an A/V receiver capable of supporting Dolby® Surround Sound audio connected to your DVR using either L/R Audio cables or an optical audio cable.
Digital PBX Phone System: Digital PBX phone systems allow many phones to share a single telephone number and are usually used in hotels and office buildings. If you are installing the DVR in your home, it is very unlikely that you are using a digital PBX phone system. Do not connect your DVR to a digital PBX phone system. Doing so may permanently damage your DVR’s modem and will void your warranty.
Surge Protector: Surge protectors are devices that protect electronic equipment from power fluctuations. Like all electronics equipment, your DVR can be damaged by fluctuations in your line voltage. Purchasing a surge protector is highly recommended. If you purchase a surge protector that allows you to plug in both your DVR’s power and your telephone cord, you may prevent damage to the parts of your DVR that are connected to your phone line as well! Surge protectors can be purchased at hardware, electronics, or general merchandise stores.
