Media
While any size card will work we recommend using a 4GB micro SD card. We also recommend that
you buy a brand name card such as Transcend, SanDisk, or Delkin. You should always buy your cards
from a reputable dealer because counterfeit cards exist and can cause recording issues.
We also recommend that you test your card before taking them out into the field.
Here is a testing procedure to determine if the card will function correctly:
1. Format the card in the transmitter.
2. Power cycle the unit.
3. Record at least 20 minutes of audio to a card with no timecode source.
4. Look at the Main Screen it should still be recording in segment #1.
Media Capacity
The TRX can use MiniSD cards, ranging in size from 128 MB to 16 GB. While any size card will work
we recommend using 4GB cards.

IMPORTANT: The transmitter will NOT record onto the card if:

•
If the card was removed while the power was ‘ON’
•
If the LOW BATTERY is being displayed.
Recording Format
The media card is formatted using a FAT32 file system. While recording, the unit places all recorded audio
in a single file on the media.
The files generated by the recorder can only be recognized by Zaxcom’s ZaxConvert program. Using
ZaxConvert will transfer the file to a Broadcast Wave or MP3 file. This utility is available to anyone for free
from the
Zaxcom website http://www.zaxcom.com/software-updates
NOTE: Regardless of the size of the card the TRX will only be able to record 254 segments on the card.
