3.1. Charging the battery

Charging the battery is done by placing the phone in the charger. A USB cable is included with the UC305W to connect the charger to the AC adapter or the PC's USB port. Charging time for the battery will depend on the status of the battery. For an empty battery it will take approx 4 hours to fully charge it. 

We strongly recommend charging the new battery up to 10 hours for the first three times for a longer battery life.

4. Powering on/off

4.1. In Off mode

Pressing the Talk OFF key (RED) for about 2 seconds will switch on your UC305W phone. A welcome screen will appear with a progress bar to indicate that it is busy. After a short while it will come up with the idle screen (see section 2.3). If a default Access Point (AP) is already configured, then it will try to connect to it, the status of this process will be indicated on the screen. 

4.2. In On mode

Pressing the Talk OFF key (RED) for 2 seconds will switch off the phone. 

5. First time Powering On

The phone requires a wireless connection to an access point to be able to make or answer calls. When powering on UC305W for the first time there are no preferred networks in the phone memory. After having connected to a network, it is possible to make IP calls within the network (Peer to Peer). However, for making calls over the internet you must have a SIP account from a SIP provider and the settings must be entered in the UC305W.

For phones with embedded SIP accounts that are factory installed, users can make internet calls immediately.

5.1. Password

To access certain menu items on your UC305W requires a password. The password is 25565075 and cannot be changed by the user.

6. Connecting to Network

6.1. Connecting to Network

From the menu, select the "Access Points" icon. A list will be shown of the available stored networks or Access Points (AP). A maximum of 4 can be stored. The bottom choice in the list is always "Search for AP's". By selecting this option, your UC305W will search for AP's and lists the results. By pressing "Connect" at a selected AP in the search result list the UC305W will try to connect to the AP. If necessary a key should be entered by the user. After connection it will be saved as a profile and the user is asked to set this as the default connection. By confirming it will search and connect to this network automatically next time the UC305W is powered on. If there are already 4 AP profiles stored in the phone and another one is connected, then it will ask the user which profile to replace. 

6.2. Roaming

During a call it may be necessary to connect to another AP with a better signal before the connection is lost; otherwise the call may be terminated. With roaming, the UC305W associated to an AP will switch over automatically to another AP with the same SSID and same authentication key. With different firmware?UC305W can be in idle mode (not in a call) or in a call (with call hand-over). During a call, the Received Signal Strength Indicator (RSSI) is measured continuously, if it is getting too low, phone will scan for other AP's. If an AP is found with the same SSID but with another BSSID and a stronger RSSI value, then the phone will try to connect to it. During this process the call will be temporarily interrupted for as long as it takes to reconnect. All found AP's with the same SSID are shown in the results and displayed as a single AP network. 

7. Entering your SIP accounts

7.1. Peer to Peer mode

If no SIP profiles are saved in the UC305W, then it automatically sets the SIP mode as "Peer to Peer". In this case you can only make calls via an IP number. 

7.2. Embedded SIP profile

As its default setting, if the UC305W has been embedded with one SIP profile at factory, then the phone will work at once when there is Wi-Fi internet service found.

12.3. Troubleshooting Tips

Here are some common solutions to problems that you may encounter during the installation and operation of the UC305W SIP Phone.


1. When I make a telephone call, the call does not go through; instead, I hear a fast busy signal.


Go through this checklist until your problem is solved: 

  • Power off your cable or DSL modem by unplugging its power adapter. 
  • Power off the wireless router by unplugging its power adapter. 
  • Power off the IP Phone by pressing and holding down the Power button for two seconds. 
  • Wait 30 seconds, and then power on your cable or DSL modem by plugging its power adapter into an electrical outlet. 
  • Wait 30 seconds. Power on the wireless router by plugging its power adapter into an electrical outlet 
  • Wait 10 seconds. Power on the UC305W SIP Phone by pressing and holding down the Power button (The RED right button) for two seconds. 
  • Reboot one of your networked computers, and check for an active Internet connection. 
  • Set up port forwarding on your router. You must specify that four port ranges be forwarded to the IP address of the IP Phone. These four port ranges are as follows: 5060-5061 (UDP), 53-53 (UDP), 69-69 (UDP), and 10000-20000 (UDP). 


2. I receive a DNS failure message on my phone.

  • To delete the current AP stored in your phone. Search new AP from beginning. Restart your wireless router as well. 
  • If the above does not solve the problem, then restore the phone to factory default settings.
  • Change to use SIP server IP address instead of using URL. Check your local internet provider as well. 


3. The key functionality on my phone is disabled.

Remove and replace the battery. 


4. There is strong interference noise during a call or the call is interrupted.

  • Is there an obstacle nearby that is blocking the signals? Move to another area. 
  • Is there data being downloaded that is affecting your phone's signal quality? Connect to another AP or stop the data download. 
  • Hang up and dial again.
