Appendix

Precautions for the USB port

● USB devices that can be used

  • Use a USB flash drive. Other USB devices (USB hubs, mice, computer keyboards, etc.) cannot be used even if they can be connected.

  • USB 1.1 to 2.0 USB flash drives can be used with this device (however, operation of all USB flash drives is not guaranteed).

The rating of the USB port is a maximum of 5 V/500 mA. Connecting a device that requires more than 500 mA of current will stop the power supply to this device.

● Connecting a USB flash drive

  • Do not remove or install the USB flash drive while data is being written to it. Otherwise, this device may stop functioning, or the USB flash drive or its data may become corrupted.

  • Before installing the USB flash drive again after removing it, wait a few seconds.

important Notice

  • When using a USB extension cable, be sure that it is 1 m or less.

Using USB flash drives

● Formatting a USB flash drive

Use a USB flash drive formatted to FAT32 or FAT16. Use a computer to format. USB flash drives formatted with other devices may not work properly with this device.

● Preventing accidental data loss

Some USB flash drives have a write-protect function to prevent accidental deletion of data. If the USB flash drive contains important data, write-protect it to prevent overwriting. Likewise, before adding data to the USB flash drive, for example, be sure to remove write protection.

● Switching off this device with a USB flash drive installed

Do not switch off this device while data is being written. Otherwise, the USB flash drive or its data may become corrupted.

Precautions for using SD memory cards

● SD memory cards that can be used

  • Use memory cards with the SD or SDHC format. (The SDXC format is not supported).

● Supported file specifications

WAV files
File extension .wav only.
Sampling rates of 44.1 kHz, 48 kHz, 88.2 kHz and 96 kHz are supported.
16-bit, 24-bit and 32-bit PCM monaural and stereo are supported.

MP3 files
Only one MPEG audio is supported.
Layer III is supported (only extension .mp3); free format is excluded.
Sampling rates of 32 kHz, 44.1 kHz and 48 kHz are supported.
Bit rates of 32 to 320 kbps and VBR (variable bit rate) are supported.

● Inserting an SD memory card

  • Do not insert or remove the SD memory card while the SD/ACT indicator is lit. Otherwise, this device may stop functioning, or the SD memory card or its data may become corrupted.

  • Before inserting the SD memory card again after removing it, wait a few seconds.

Using SD memory cards

● Formatting an SD memory card

  • Use an SD memory card formatted to FAT16 for SD or formatted to FAT32 for SDHC. Use a computer to format. SD memory cards formatted with other devices may not work properly with this device.

● Preventing accidental data loss

  • SD memory cards have a locking switch to prevent accidental deletion of data. If the SD memory card contains important data, lock it to prevent overwriting. Likewise, before adding data to the SD memory card, for example, be sure to unlock it.

● Switching off this device with an SD memory card inserted

  • Before switching off this device, make sure that the SD/ACT indicator is not lit. Otherwise, the SD memory card or its data may become corrupted.

Distance to furthest DCP control panel

The distance from the DME7 to the furthest DCP control panel depends on the number of connected DCPs.

Example 1. When there are 8 DCP devices

dcp1

Example 2. When there are 2 DCP devices

dcp2

For the relationship between the number of connected devices and the distance, refer to the following table.
