Using an optional ChargePAK
ChargePAK makes your Pure radio truly portable, so you can enjoy the programs you love in the yard or at
the beach.
Because it’s rechargeable ChargePAK is much cheaper than regular batteries. It’s also more eco‑friendly
because it reduces the amount of toxic substances sent to landfill. And, because it’s a fit‑and‑forget
solution that charges whenever your radio is connected to the power outlet, it’s much more convenient
than standard rechargeable batteries.
Installing a ChargePAK
1. Switch your One Flow off and disconnect it from the power supply.
2. Open the battery compartment and push the ChargePAK connector plug into the socket in the
compartment. Line up the ridges on the plug with the slots in the socket. Do not force the plug.
3. Insert ChargePAK into the battery compartment.
4. Replace the battery door and connect your product to a power outlet.
5. ChargePAK will begin charging. When charging your ChargePAK for the first time or after an
extended period of inactivity we recommend that you charge it for around 24 hours to ensure full
battery power.
Note: It is normal for your ChargePAK to get warm, especially during charging. Your ChargePAK will give
years of trouble‑free use under normal circumstances, but like all rechargeable batteries its efficiency will
gradually reduce with age.
Important: One Flow can only be powered with a Pure ChargePAK E1 and is not compatible with any
other batteries, either disposable or rechargeable, or any other ChargePAK model.
A
Li-ion 3.7V 8800mAh 32.56Wh
Do not tear or remove the plastic covering or any part of
the ChargePAK.
Only use in Pure products with original Pure power adapters.
For your safety, always use a genuine Pure ChargePAK.
The pack will become warm during charging.
Caution: May explode if damaged or disposed of in fire.
Must be disposed of properly. Do not short-circuit.
Refer to your product documentation for details of how to
install and use ChargePAK.

Help and advice
I am having trouble connecting to my network
• Your radio can’t connect to wireless networks that are access controlled, such as office networks,
without a WEP, WPA or WPA2 key or password.
• Your radio needs to be positioned within the range of your wireless network, which will be reduced if
there are walls between your router and radio. Although One Flow is very good at picking up wireless
networks, the strength of the Wi‑Fi signal will vary depending on your router and the surrounding
environment. If One Flow fails to find your wireless network, or the signal drops off, move the radio
closer to the router.
• Unless your wireless network is ‘open’ (this is generally not recommended due to the risk of
unauthorized access), make sure you have your WEP, WPA or WPA2 key to hand.
• If you also experience trouble connecting to your network with the Ethernet adapter, check your
Internet connection using a computer. If this is OK, try restarting your modem.
Screen displays ‘Station not available’
• If a station will not play visit http://support.pure.com for assistance.
