Powering Your ER310
USB Charge Cable: Before the ER310 is used, the internal
rechargeable battery pack should be charged with the USB charge
cable until the battery indicator icon indicates a full charge. To
charge the ER310 with the USB cable, switch the power source
switch to the “Li” position. Then, insert the USB charge cable into
a USB power source and plug the micro USB connector into
the port labeled “USB In” on the side of the radio. The CHARGE
indicator light will be lit when the USB charge cable is plugged
in. The battery icon on the LCD will flash as the battery charges.
When the Li-ion battery has reached full charge, the battery icon
will stop flashing and will have 3 bars. It will take approximately
5.5 hours to recharge a completely depleted battery pack using the
USB charge cable.
Rechargeable Battery:The included rechargeable battery
is located in the battery compartment and is charged by turning
the hand crank, exposing the solar panel to sunlight, or by using
the USB cable to attach to a USB power source. The battery is
specified as 3.7 VDC, 2600 mAh, lithium ion (Li-ion).
Warning:
• Only use Midland’s Li-ion battery pack.
• Do not attempt to charge alkaline batteries or any battery packs
other than the ones indicated in this manual. This could cause
leakage and damage to the radio.

ER310 Power Sources Continued...
Dynamo Power: Turning the hand crank charges the built-in
Li-ion battery pack. To charge the radio using the hand crank,
make sure the power source switch is in the “Li” position and start
turning the crank. The CHARGE indicator light will be lit while
the unit is being cranked. Speed of cranking and length of time
cranked will determine the charge of the Li-ion battery. The battery
icon on the LCD will flash as the battery charges. When the Li-ion
battery has reached full charge, the battery icon will stop flashing
and will have 3 bars. One minute of cranking gives up to 9 minutes
of radio use time.
Solar Panel Charge: Make sure the power source switch is
in the “Li” position. Then, place the ER310 where the solar panel
is exposed to direct sunlight. One hour of solar charging in optimal
sunlight conditions gives up to 45 minutes of radio use time. The
battery icon on the LCD will flash as the battery charges. When
the Li-ion battery has reached full charge, the battery icon will stop
flashing and will have 3 bars. The CHARGE indicator light will be
lit while the unit is charging.
AA Battery Operation: The ER310 is designed to operate
on six AA batteries (not included). To power the ER310 on its
AA batteries, flip the power source switch to the “AA” position.
Warning: For long-term storage, it is recommended that the
AA batteries be removed to prevent leakage and damage to
the ER310.

Using the Weather Radio
About NOAA/NWS
The National Oceanic Atmospheric Administration and the National
Weather Service operates a system of weather and hazard alert
broadcasts covering most of the United States. Typical broadcasts
are within reception distance of 25-50 miles of the weather
station. Fully extend the telescopic antenna and rotate until
reception is clear. The ER310 can receive broadcasts up to 50
miles from the weather station depending on your location and
conditions of weather, terrain, etc. If reception is not good, try a
different location to find a spot of improved reception. If indoors,
placement near a window usually improves reception. If a weather
broadcast cannot be heard on any of the 7 channels, contact your
local NOAA/NWS office and verify the closest station is on air.
Their web site is http://www.nws.noaa.gov/nwr/.
Selecting a Weather Channel
The ER310 has 7 NOAA/NWS weather channels to choose from.
• Press the BAND button to select the weather band.
• Then use the TUNE buttons to select the strongest weather
channel in your area.
Ch. # Frequency
