PDR-W839
7.1.4 ERROR MEESAGE "CHECK TEMP"
If recording is operated on the PDR-W839 in high or low temperatures, a message "CHECK TEMP" is displayed for several
seconds, the operation halts, and then afterwards the display changes to "MONITOR".
This message is displayed to indicate what happens to recording and playback operation if the product is placed on a hot object like
an amplifier or in a closed space like a rack in which an object omitting heat such as an amplifier would make it even hotter. If the
product is moved to different temperature, the problem disappears. When the temperature sensor inside the product hits +70°C or
higher, or -15°C or lower, the message is displayed. Once displayed, all actions stop. In addition, the product will be warmer than
the temperature outside the casing and the outside product threshold temperature would be a little lower. These temperatures are
not specifications that guarantee operation.
