NOTES:
1. The normal operating temperature range is that at which the transmitter meets all specifications. The extreme operating temperature
range is that at which the transmitter remains powered without damage.
2. All transmitters with fluorinated oil filled cells can only be operated in temperatures from -10° to +80°C (+14° to +176°F).
3. The normal operating temperature range for the LCD is that at which the LCD remains functional. Exceeding those conditions may cause
the LCD to go blank. The transmitter remains functional to its operating limits. When the temperature returns to the acceptable range, the
display is restored; however, the life of the display may be reduced.
4. The minimum supply voltage necessary to support communications is 17.0 VDC.
5. Add 0.4 VDC to all minimum supply voltage values if using the lightning arrestor option.
6. Refer to Table 1-4 for the ambient condition limits for certified applications.
7. The transmitters are only certified for those agencies and classes indicated on the certification label. Do not install the transmitters in
locations for which they are not suited. Refer to nomenclature position 12.
